The Impossibles arrived at the museum, and right away, noticed the break in point. There was a small hole smashed in the window.

"Who could fit through that?" Coiley asked.

"Normally, I'd say the Sinister Speck," Fluey said. "But the hole's too big for him. I'll go in first and unlock the doors for you guys, then we'll search."

"Right," Coiley and Multi said in unison.

Fluey converted into liquid, and went in through the hole in the window. Then he went to the front doors and unlocked them. Coiley and Multi walked into the museum, and they searched around to see what had been stolen. To their surprise, it didn't look like anything.

"You'd think there'd be something stolen around here," Multi said.

"Wait a minute," Fluey said. "Look over there in the space exhibit."

The boys looked, and saw a bat, trying to fly off with a rock from the moon that space travellers had brought back recently.

"A bat?" Coiley asked.

"Come on, let's get it!" Multi shouted. "Rally ho!"

Multi duplicated forward and tried to swat the bat with his shield, but the bat began screeching and few upwards with the rock. Multi duplicated himself up to catch it, but the bat swooped at him, dropped the rock, and began pulling at his hair with it's feet.

"Hey!" Multi shouted, trying to swat at the bat. "Get this overgrown rat out of my hair!"

"I'll get it, Multi," Coiley said, stretching his arm forward, and tried to grab the bat. It screeched, and bit him in the hand.

"Ow!" Coiley shouted. "I hope that thing doesn't have rabies!"

"Let's see how far our flying friend can get when his wings are wet!" Fluey shouted. "Rally ho-ho!"

Fluey converted from solid to liquid, and shot forward. The bat flew towards him, grabbed his goggles with it's feet, and pulled them forward. Then, it let go, and Fluey's goggles were snapped back into his face.

"Ouch!" Fluey shouted. "Oooh, man, that hurt!"

The bat let out a girlish giggle, picked up a bag, and flew away. Fluey adjusted his goggles, and ran after the bat. Multi and Coiley followed. They managed to trace the bat outside, but they lost sight of it.

"Where'd that flying rodent get to?" Fluey asked.

"I don't know," Coiley said, picking up something off the ground. "But it dropped the moon rock."

"We'll take it back to the museum tomorrow," Multi said.

The bat, in the meantime, flew into the woods, and in a puff of purple smoke, turned into Danalleah. She pulled out the list, and then the bag.

"Let's see here," she said. "Fly thighs, lizard gizzards, whale tails, bee knees, bear hairs, eel heels, crow toes, spider eyebrows, and the moon rock. But . . . where's the rock? Oh broomsticks, I must've dropped it! I'd better go get it or else Mother will be very angry with me!"

One puff of purple smoke later, Danalleah transformed herself back into a bat, and flew off, retracing her steps, trying to locate the moon rock. She spent the rest of the night, and the rest of the next day trying to find it, but she couldn't.

"Oh hexes!" she shouted as she flapped around. "I can't find it! Those stupid boys I ran into must have returned it already! I'd better go back to the museum and get it!"

Danalleah flew back to the museum, and snuck in through a vent. She went all around the space exhibit, but the moon rock wasn't there, either. She exited the museum, and continued her search, when suddenly, someone grabbed her in midair, and that someone was Cronella Critch.

"What is taking you so long?!" she demanded.

"You told me to get everything on the list, Mother," Danalleah said. "But I've misplaced the moon rock."

"You've misplaced the moon rock?!" Cronella screeched. "Well, you'd better find it and bring it back!"

"Yes, Mother. I will, Mother!"

Cronella let go, and Danalleah flapped off. She came to the community center, and saw a bunch of people going in. And a lot of them happened to be ghosts, witches, and monsters.

"Hmm, I wonder if there was some sort of get together that I didn't know about?" she asked. "I'd better look into this."

Danalleah hovered closer to the ground, and turned herself back into her human form. Then she walked inside of the community center, and looked around. There was an assortment of strange creatures inside. Witches, wizards, black cats, Frankenstein monsters, vampires, princesses, werewolves . . . . you name it. Danalleah was a bit speechless.

Meanwhile, the Impossibles, plus Shawn and FG, were setting up for the Impossibles' set.

"Did you guys return that moon rock yet?" Shawn asked.

"Nah, we didn't have a chanth to," Fluey said. "We've been buthy all day with reherthalth and helping thet thingth up for the party."

"What?" Shawn asked.

"He said we were busy with rehearsals and helping set up for the party that we didn't get a chance to return the moon rock yet," Coiley, who had decided to come to the party as a Frankenstein monster, said.

"I wish you hadn't found those fangs in your aunt's attic, Fluey," Multi commented.

"What kind of vampire would I be if I didn't have the fangth?" Fluey asked.

"How are you going to sing with those fangs in your mouth, anyway?" FG asked.

"I'll improvithe," Fluey said.

"Well, improvise quick," Shawn said. "Time to get the show on the road."

"Right," Fluey said. "Let'th hit the bandthtand and thtart thinging."

"What?!" Shawn shouted.

"Fluey, take those teeth out of your mouth!" Multi shouted. "We can't understand a word you're saying!"

"All right, all right," Fluey grumbled, taking the vampire fangs out of his mouth.

"Besides," Coiley said. "If you leave those things in, you'll be lithpig and thpitting all over the microphone."

"Yeah, very funny, Coiley," Fluey said, wiping his eye. "Just do me a favor. Say it, don't spray it."

The others laughed, and the boys got to the bandstand and began playing. Everyone in the community center started to dance. Danalleah just stared at them all as if they were crazy. Then she walked closer to the bandstand, and stared at the Impossibles. Then she caught sight of Fluey. And she found she couldn't take her eyes off him. Fluey felt like he was being stared at, so he glanced around, and spotted Danalleah looking up and making goo-goo eyes at him. It made him a little uneasy, but he kept on playing anyway. Once they were finished with their set, the boys separated while someone put some music on the stereo system. Immediately, Multi and Shawn hit the dance floor. Coiley and FG followed them. Fluey just sat on the sidelines, watching them. He saw Danalleah walk up to him, and he stood up.

"Hi, hot stuff," she said. "Want to dance?"

"Yeah, why not?" Fluey said, shrugging. He and Danalleah walked out onto the dance floor and began dancing. Danalleah was doing a version of the classic Twist.

"This is called the Transylvanian Twist," she said.

"I thought they changed the offical dance to the Monster Mash," Fluey commented.

"Can I ask you something?"

"Okay."

"If you're a vampire, what happened to your fangs?"

"My friends made me take them out. They couldn't understand what I was saying if I left 'em in."

"Take them out?"

"Yeah, you know, fake fangs."

"Oh. So what part of Transylvania are you from?"

"What?!"

Fluey stopped dancing, and gave this girl a weird look. Danalleah was a bit flustered at his reaction, so she cleared her throat, and tried again.

"My name's Danalleah," she said.

"Danalleah?" Fluey repeated. "Wild name. But I'm one to talk. Mine's Fluey."

"You must not be from Transylvania, then."

"Uhh, no, I'm not."

"But all the vampires I know are from Transylvania. And all the vampires I know don't wear fake fangs."

"Okay . . . . we've got a live one here."

"Also, I find it very strange to see all these witches and ghosts and monsters here. And these witches . . . . I've never seen any of them before . . . . and none of the witches from my troop are here . . . . not to mention I keep seeing giant cats around."

"Okay, that does it. I don't know who you are, or what you've been drinking, but you're really creeping me out. Sheesh, some people take these costume parties waaaayyyy too seriously!"

"Costume party?"

Fluey left Danalleah standing there, and went back to the bandstand. She ran after him, but stopped when she saw him open his guitar case. Inside was the moon rock. Danalleah then realized something. This cute vampire she had her eye on wasn't a vampire at all. He was the boy with the green wetsuit and the goggles she ran into at the museum. She realized something else, too. The other two boys in the band were the same boys that stopped her from getting the moon rock at the museum. Danalleah had to get it now, but she didn't necessarily want to run over and just grab it. So, she ran outside, and turned herself into a bat. Then she flew back into the community center, and straight into Fluey's face, in order to get him away from his guitar case.

"Hey!" he shouted, trying to wave the flying rodent out of his face. Danalleah ended up pushing him to the edge of the stage, and caused him to fall off of it. CRASH! Danalleah hated to do that, but she had to get that rock.

"Hey, Fluey, you all right?" Coiley asked as he and the others ran over.

"Yeah," Fluey said, standing up. "But take a look."

"It's that bat again," Multi said.

"You guys better do the quick change thing," Shawn said. "FG and I will cover for you."

"Right," Coiley said. He and Multi regrouped with Fluey, and the three of them ducked backstage so they wouldn't be seen. They didn't want to reveal their secret identity in a room full of people, that was for sure.
