Mitzi was back at the Dojo after receiving a call from the EPF telling her that she would be training with more Elite Puffles. She entered the Puffle Training Room, when she saw something very peculiar. It was PH, sleeping in a giant bubble. Mitzi knew that living in a bubble was not a good idea, because someone would suffocate due to the lack of air. She decided that it was best to wake PH up to start the mission.

"Sorry, PH, you have to wake up," said Mitzi. "We've got work to do."

But PH didn't hear Mitzi and continued to snooze. Mitzi walked up to the bubble and began to lightly tap on it.

"Excuse me..." she said. "I'm here for my training..."

"Huh, what?" said PH as she woke up. "Well, I'll be a brumby...It's you, Mitzi! Thank goodness you're here."

"Why were you sleeping in a bubble?" asked Mitzi.

"Well, the two puffles you were supposed to train with decided to skip training today," said PH. "One of 'em put me inside this bubble to get away! I reckon I've been in here for a while to have fallen asleep..."

"Hold on," said Mitzi. "I'll pop that bubble for you!"

"Hang about, mate!" said PH. "Bubbles like this one are super strong, so you'll need something super pointy to pop it."

"No problem," said Mitzi. "There's got to be something pointy around here I could use."

Mitzi looked around to see if she could find anything to pop the bubble. There was a heavy weight that seemed too heavy for Mitzi to pick up on her own, a jetpack with an antenna and a remote control, and a broken bamboo shaft. The bamboo shaft might do the trick, so she picked it up and gently poked the bubble with it. Instantly, it popped, and PH was free.

"Thanks for letting me out, mate!" said PH. "I thought I'd be in there for days!"

"Why do you think the puffles wanted to skip their Elite training?" asked Mitzi.

"They're right good puffles," said PH. "But they won't work with just anyone."

"What could I do to get them to come back?" asked Mitzi.

"Maybe go and have a look for 'em," said PH. "I'll stay here in case one comes back."

So, Mitzi decided to search for the puffles. The first place she looked was on the Iceberg, but there were no puffles in sight. She checked the Pet Shop at the Plaza next, because that's where puffles normally hung out, but the shop was closed. Next to the Pet Shop was the Theater, so Mitzi decided to go in there to see if any puffles were trying out for a play. When she entered, she saw a huge racket. There was a runaway jackhammer ripping through the stage.

"What's all this?" she asked.

"My set! My set!" cried the panicking stage director. "Do something, please!"

"It's moving too fast to catch!" said a construction penguin. The jackhammer was moving around like crazy. Mitzi wanted to help, but she didn't know how. She decided to come back to it once she found one of the Elite Puffles. Maybe it could help her stop the jackhammer. She checked the Forest and the Snow Forts, but there weren't any puffles there. The Ice Rink was nearby, so Mitzi decided to check it out. When she got there, she saw a pink puffle wearing a cowgirl hat lassoing a rope in the air, while a penguin with a foam flipper was cheering her on.

"Loop puts on a great lasso show," said the penguin. "I'm Loop's number one fan! Gooo, Loop!"

So the pink puffle's name was Loop. No doubt she was one of the Elite Puffles that Mitzi had to train with.

"What do you like about Loop so much?" asked Mitzi.

"I've always been a fan of rhythmic gymnastics, you know," said Loop's fan. "And no other puffle I've seen can do what Loop can!"

"How could I convince Loop to come with me?" asked Mitzi.

"I dunno," said Loop's fan. "Maybe if you scored a goal against my buddy. It's pretty much impossible to do alone."

"What do you say, sport?" said the goalie penguin. Got what it takes to break through my awesome defense?"

"I'd try," said Mitzi. "But I don't have a hockey puck."

"I can deflect anything you throw at me," said the goalie penguin. "Even snowballs."

"Anyone ever hit a shot past you?" asked Mitzi.

"Yes," said the goalie penguin. "But it really takes good teamwork to score a point on me."

Teamwork? Well, that seemed pretty easy. Mitzi knew just the puffle to team up with to hit some shots past the goalie penguin. She took out her whistle and blew into it, summoning Bouncer.

"Okay, Bouncer, here's the plan," said Mitzi. "Let's try to score some goals by throwing snowballs into the net."

Bouncer juggled some snowballs to throw in the net, but the first one she threw missed the net and hit the goalie instead.

"Nice try, buddy!" said the goalie. "I'm just too quick with my defense!"

Bouncer threw another snowball, which didn't hit the goalie, but nearly slammed into the rim of the net.

"Almost had me that time!" said the goalie. "Giving up already?"

Mitzi and Bouncer weren't giving up. The blue puffle threw one more snowball which knocked the goalie off his feet and went right into the net.

"Wow, great shot!" said the goalie. "You and that blue puffle make a great team."

"This is Bouncer," said Mitzi. "Do you think we got Loop's attention?"

"Sure thing," said the goalie. "Loop is in total awe! I think her number one fan might be a little surprised, too!"

"I couldn't have done it without Bouncer!" said Mitzi proudly.

Suddenly, she heard her Communicator ringing. Someone was trying to call, so she immediately answered. The caller was Dot.

"Agent D here," said Dot. "How did things go with Loop?"

"Loop is a high energy puffle!" said Mitzi. "Have you seen her amazing lasso tricks?"

"I remember the first time I met Loop," said Dot. "That puffle had me jumping rope all day!"

The next penguin to call Mitzi was PH.

"Everything's ready," she said. "Were you able to convince any puffles to return for training?"

"Yes, ma'am," said Mitzi. "Loop is ready for training."

"Excellent," said PH. "I'll use my Spy Gadget to warp you back to the Puffle Training Room now."

"All right," said Mitzi. "Let's get to it!"

In a few seconds, Mitzi and Loop were warped back to the Dojo, where PH was controlling the remote-controlled jetpack.

"You're back with Loop, Mitzi!" said PH. "Good show, mate! That's totally awesome."

"Thanks!" said Mitzi. "I couldn't have done it without Bouncer's help."

"Good call, mate," said PH. "The best agents know how important it is to work with their puffles. Now, let's train with Loop. She uses a lasso to catch moving objects. If she catches the jetpack, the rope will stop it so you can get a closer look."

"Got it," said Mitzi. "I'm ready to work with Loop now."

Then she turned to Loop and said, "Okay, Loop, can you catch the jetpack with your rope?"

Loop pulled out her lasso, twirled it around a few times, and caught the jetpack, slowing it down.

"Nice catch!" said PH. "Now that you've trained with Loop, you can use her lasso to catch moving objects."

"What should I do next?" asked Mitzi.

"You should go find Pop, the other picky puffle," said PH.

"Where should I look?" asked Mitzi.

"Pop's a purple puffle that loves music..." said PH. "Pop music, to be exact. That's one of the reasons she got her name. You'll find Pop anywhere there's a good dance beat."

"What will you do while I'm out looking?" asked Mitzi.

"I'll be getting your training tools ready," said PH. "Remember to use your whistle if you need a puffle partner."

And so, Mitzi left the Dojo to find Pop. PH said that Pop could be found anywhere that played music with a good dance beat, and Mitzi knew exactly where to look: The Dance Club. It was located in the Town, right in between the Coffee Shop and the Clothes Shop. It always had good dance music, so Mitzi decided to go there and see if she could find the purple puffle. When she arrived, she saw a black penguin working as a bouncer and a pink penguin looking eager to get in.

"I've been practicing my sweet dance moves!" said the pink penguin.

"What kind of sweet dance moves?" asked Mitzi.

"I bust a move in my Gamma Gal costume, then light up the club with my Plasma Glow Wave," said the pink penguin. "It's awesome!"

"Are you here for the Dance Club party?" asked the bouncer penguin. "You'll need to wear appropriate attire. That layered lavender top and denim skirt aren't going to cut it, miss."

"Really?" said Mitzi, looking at her clothes. "What kind of attire do I need?"

"They've gotta be fancy dance clothes," said the bouncer penguin. "This here is a fancy party."

"Is there a purple puffle inside the Dance Club?" asked Mitzi.

"There sure is," said the bouncer penguin. "That puffle can dance, friend."

"I'm on it," said Mitzi. "I'll pick out the nicest clothes I can find."

"Well, that's a good thing," said the bouncer penguin. "Because it's fancy clothes only."

The Clothes Shop was right next to the Dance Club, so Mitzi decided to buy a fancy outfit to wear in order to enter the club. But for some reason, the shop was closed. She checked the Sports Shop, but they didn't have a catalog for her to choose from. But then she remembered that the Theater always had some fancy costumes that the actors wore in plays. She decided to go there and ask if she could borrow a costume. She walked in and saw that the jackhammer was still on the loose, but luckily, she had Loop by her side, so she knew what to do.

"Hey, Loop, do you see that jackhammer ripping through the stage?" she asked the pink puffle. "It's time for you to catch it with your lasso! Go on, catch it!"

Loop twirled her lasso in the air and caught the jackhammer, slowing it down to a stop. The stage director and the construction penguin were impressed.

"Wow," said the construction penguin. "You totally saved my noggin like a hard hat on a windy day."

"Oh, I am so wonderfully relieved that the set wasn't damaged," said the stage director.

"Glad to help," said Mitzi.

"I look forward to the day when I may return the favor," said the stage director.

"Can I ask about costumes now?" said Mitzi. "I need a fancy outfit for a party."

"Ah, yes!" said the stage director. "I have just the thing for you. Open up the costume trunk and pick out some fancy clothes for your wardrobe."

"Cool, thanks!" said Mitzi as she went to the costume trunk to pick a fancy outfit.

"It's the least I can do," said the stage director.

Mitzi opened the trunk to find some good clothes to wear. There was a lot of fancy stuff in the trunk, but it didn't take long for her to find a fancy outfit. She settled on a pink dress with sparkly sequins.

"Nice dress," she thought. "Doesn't get much fancier than this."

She went to the Sports Shop and entered one of the changing rooms to change into her fancy dress. She didn't bother to change her shoes or her hair, because she thought her pink sneakers were perfect for dancing and her pigtails were her trademark look. She went back to the Dance Club, hoping that she would be able to get in with her new outfit.

"Fancy clothes you've got there," said the bouncer penguin. "You might be the most stylish one in there. Have fun!"

Mitzi was thrilled that she could enter now, and the bouncer didn't even question her hair or shoes. She went in, where she saw some penguins - and a puffle - hitting the dance floor while the DJ spun some tunes.

"Hey there," said the DJ. "Got a special request?"

"What do you know about the purple puffle over there?" asked Mitzi.

"I know Pop can't resist a good old-fashioned dance challenge," said the DJ.

"Dance challenge?" said Mitzi.

"Yeah," said the DJ. "Pop loves to watch dance competitions. You should try it sometime."

"No time like the present," said Mitzi. "I'll go check it out."

"Alrighty then," said the DJ as he resumed spinning his tunes. "Go out there and bust a move!"

So, Mitzi knew that if she wanted to bring Pop back to the Dojo to train, she would have to make some best moves. It wouldn't be too hard, because she was a good dancer. As Mitzi went to the dance floor, she saw a pink penguin wearing a disco outfit dancing with a purple puffle wearing star-shaped sunglasses. That puffle must have been Pop.

"Woo! Yeah! That's right," said the disco penguin as he watched Pop spin around like a little purple tornado. "This song's groovalicious! What do you think?"

"Um...yeah, it's a pretty good song," said Mitzi. "Say, do you know anything about that purple puffle?"

"It's hard to get this purple puffle excited," said the disco penguin. "I've been dancing my flippers off but nothing works!"

"Well, how about we dance together?" asked Mitzi.

"I thought you'd never ask!" said the disco penguin. "Let's shake it like a jackhammer!"

"I'm in!" said Mitzi as the dance challenge started. It was time to pull off some of the best moves she had. As the disco penguin danced, Mitzi memorized his moves and copied him. It was fairly easy and fun, and she proved to be a better dancer than the disco penguin because, towards the end of the challenge, she wowed the crowd with her amazing breakdancing skills. Even Pop was amazed.

"Those were some smooth moves!" said the disco penguin.

"You think so?" said Mitzi. "Thanks!"

Pop liked Mitzi's dance moves, too, because she was bouncing around happily. Now, it was time to hurry back to the Dojo to finish their training session. Suddenly, before Mitzi could take Loop and Pop out of the Dance Club, there was a very loud crash. The dancers all froze in place and the DJ immediately stopped the music.

"Whoa, that was a huge crash!" said the DJ. "It even scratched my records for me!"

"It sounded like it came from the Boiler Room below!" said Mitzi.

"Should we check it out?" asked the DJ.

"Yes," said Mitzi. "Let's investigate."

"No way!" said the disco penguin. "I'm not going down there!"

"You stay here and keep an eye on the Dance Club," said Mitzi. "The DJ and I will check it out."

"I'm sorry," said the disco penguin. "That sounded a bit scary. I'll wait here."

Mitzi and the DJ went into the boiler room to investigate the source of the crash. When they got there, they saw that the boiler was missing. Apparently, it wasn't securely fixed to the ground, because something must have happened to it.

"What happened here?" asked Mitzi.

"The boiler is gone!" exclaimed the DJ. "How could this happen?"

"There must be a clue around here somewhere," said Mitzi. "A boiler doesn't just get up and walk away..."

Puffle training was going to have to wait. Mitzi looked around to see if she could find any clues. There was a filing cabinet that had been knocked over and was now blocking the entrance to the underground pool, which was broken. There was something underneath the filing cabinet, but it was too heavy for a penguin to lift. For some weird reason, Pop was staring at the cabinet, because she could lift it for Mitzi with a giant bubble. She got out a bubble wand a blew a bubble big enough to trap the filing cabinet in, which then lifted up into the air.

"Wow!" said the DJ. "That puffle's bubble lifted it up!"

"Now that's one strong bubble!" remarked Mitzi.

"Hey, something's underneath it!" said the DJ, pointing to the ground.

"I thought I saw something..." said Mitzi.

"Now we have to clean up," sighed the DJ. "So much for the party..."

"Was the door to the pool broken before?" asked Mitzi.

"No," said the DJ. "I bet whoever stole the boiler broke the door when they were making their getaway."

"What do you plan to do?" asked Mitzi.

"I'm gonna chill down here and make sure no one messes with that big bubble," said the DJ.

"Fair enough," said Mitzi. "I'm going to see if I can track down the boiler...And who took it."

"Good luck," said the DJ. "And thank you for all your help."

Underneath the filing cabinet was an empty oil can. Mitzi picked it up, remembering that the Jetpack Guy found one of those earlier. She went past the underground pool and into the mine, where she saw Dot inspecting a deflated inner tube.

"Mitzi! What are you doing here?" she asked.

"Following a trail of clues," said Mitzi. "Are you looking for the missing boiler, too?"

"Missing boiler? No, not at all!" said Dot.

"No way..." said Mitzi in disbelief. "More things are going missing?"

"I'm afraid so," said Dot.

"Who could have done this?" asked Mitzi.

"I don't know," said Dot. "This deflated inner tube must be a clue."

"Do you think this empty oil can has anything to do with it?" asked Mitzi, showing Dot the oil can.

"Another empty oil can?" said Dot. "The Jetpack Guy found one after you rescued the Rookie!"

"We should tell the Director about this," said Mitzi.

"Indeed," said Dot. "I'll warp us there using my spy gadget."

When Mitzi and Dot returned to the HQ, they headed over to the Command Room and discussed what they found with the Director.

"A missing boiler...The Aqua Grabber out of commission..." said the Director. "And only an empty oil can and a deflated inner tube thus far?"

"Yes, Director," said Dot. "These clues are all we have at this point."

"I sense a great disturbance on the island," said the Director. "I am going to direct all available EPF agents to the distress sites."

"I'll go right away, Director," said Mitzi.

"Not quite, Agent Flapdoodle," said the Director.

"But, Director," said Dot. "Mitzi did such a good job working with the puffles!"

"I agree with you, Agent D," said the Director. "This is why I want Agent Flapdoodle to complete puffle training right away. Once puffle training is complete, she will be ready for the case."

"I understand, sir," said Mitzi.

"The Puffle Handler is currently in the field," said the Director. "Meet the Jetpack Guy at the Beacon and he will take you to the Puffle Handler."

Mitzi was willing to complete her puffle training so she could help the other agents find out who or what was causing chaos around Club Penguin. For now, she was going to have to wait until the next mission to continue training. These missions were getting very interesting, and Mitzi liked going on them. Who knew where her next mission was going to take her?
