Silas and Valerie were at the AVL. They were tracking the main villains until they saw something that was unfamiliar.
"What is that?" Silas asked. "It looks like one strange house." Valerie said. "Should we call Agent Gru and Wilde?"
Silas nodded. "Yes." He said. Valerie called Gru.
Gru and Lucy ran in. "What happened?" Gru asked. "Is everything okay?" Lucy asked. "You two need to see this." Silas said.
Gru and Lucy looked at the monitor and saw a strange small house. "Who's house is that?" Lucy asked. "We don't know, but we want the two of you to find out and stop this person if they're a villain." Valerie said.
"We'll find out. Come on Lucy." Gru said. "Coming." Lucy said. The two AVL agents left.
In the house, there was a green alien with his little robot friend. The alien happened to be an Irken. His name was Zim and his little robot friend was named GIR.
They heard the doorbell. "Ooh. Doorbell." GIR said. "GIR, get in your disguise!" Zim yelled. "Okay." GIR said and he it got into his disguise and opened the door.
Lucy saw GIR in his disguise. GIR's disguise is a little green dog. "Aw. You're so cute." Lucy said. "Hello." GIR said.
"Oh look. A talking green dog. How cute is that?" Lucy asked. Gru was suspicious. He knew dogs weren't green and they don't talk.
"Wait a minute Lucy. Dogs don't talk. They also aren't green." Gru said and he took his Freeze Ray out. "How do you know, and who are you?" Zim asked. "Gru." Gru said.
GIR saw the Freeze Ray and he thought it was Gru's pet. "I love you." He said. "What?" Gru asked. Lucy chuckled. "I think the little dog likes your Freeze Ray." She said.
"This is ridiculous. What are you?" Gru asked. "I am Zim!" Zim yelled. "Are you some kind of alien?" Lucy asked. "I'm an irken." Zim said.
A boy who looked like the same age as Zim was spying on him, GIR, Gru, and Lucy. His name was Dib. He gasped. "Yes! These two people are suspicious about Zim too." Dib said. "I've got to tell Gaz." Dib ran home.
Gaz, Dib's younger sister, was at home and she was playing a video game. Dib ran into the house. "Gaz! Two people are also suspicious about Zim!" Dib yelled. "Can't you see I'm playing a game?" Gaz asked.
"I know, but this is more important!" Dib yelled. "I don't really care Dib." Gaz said. "Gaz, this is very important to me." Dib said.
"So?" Gaz asked. "The two people are going to a place called the Anti-Villain League. We need to go." Dib said. "And why do I care?" Gaz asked.
"If you come with me to the AVL, we'll go to Bloaty's." Dib said. "Fine." Gaz said.
Dib took his sister to the AVL where Gru and Lucy were.
"Who was in the house?" Silas asked. "An irken named Zim." Gru said. "Irkens? This sounds like an invasion." Silas said. "There also was this cute little green dog who goes by the name GIR." Lucy said.
"GIR?" Valerie asked. "Yeah. He's a cute little green dog who talks." Lucy said. Valerie sighed.
"Agent Wilde, what are you talking about? Dogs do not talk." Silas said. "Yeah and they're not green." Valerie said.
Zim was in his base. "Filthy human! I am Zim and I will destroy you!" Zim yelled. "But I like the bald guy." GIR said. "GIR! I'm being serious!" Zim yelled.
Dib and Gaz walked into the AVL. "Gaz, look." Dib said. "Why should I?" Gaz asked. "Gaz, please listen to me. We're the only ones who know about Zim's secret and now these people know as well." Dib said.
Gru had his arms crossed. "I'm telling you Gru. The green dog is so cute." Lucy said. "He might be, but what about that alien?" Gru asked.
"Oh my gosh. Hey Gaz, this guy doesn't like Zim either." Dib said. "I don't like you. Now can we go to Bloaty's?" Gaz asked. "Not yet. I've got a few questions for him." Dib said.
GIR was watching TV without his disguise. "GIR, I'm going to my lab for a minute. Don't let any intruders in our base." Zim said and he walked away. "Okay." GIR said.
When Zim was gone, GIR jumped off the couch, put his little green disguise on, and left the house. He took a little walk by himself and of course, Zim didn't know.
During his little walk, GIR saw a black house. "Whoa." He said. He walked to the house and rang the doorbell.
A teenage girl named Margo opened the door. "Hello?" She asked. "Hi." GIR said. Margo was shocked. Did that dog just talk?
Then she thought her sister was up to this. "Very funny Edith. I told you not to prank me." Margo said. "What are you talking about?" Edith asked.
The girl wearing a pink hat walked over to Margo. "What?" She asked. "Explain this." Margo said and she pointed to the green dog.
"All I see is a green dog." Edith said. "Your green dog." Margo said. "It's not mine." Edith said. "Agnes." Margo and Edith said. "Agnes, come over here." Edith said.
A little seven year old child walked out of the house. "Can you explain why one of your little friends are out of the house again?" Margo asked.
Agnes looked at GIR. "Aw. Who's this cutie?" She asked. "What are you talking about? It's yours." Edith said. "No. I haven't seen him before, but can we keep it?" Agnes asked. "Yeah can we?" Edith asked.
Agnes and Edith looked at their older sister. "I don't know guys. There's something off about this dog. First of all, dogs are not green." Margo said.
"It could be one of Dr. Nefario's experiments." Edith said. "Maybe, but he never mentioned about a green dog." Margo said. "True." Edith said. "You think it escaped from El Macho?"
"No. El Macho used purple serum, not green." Margo said. "And you know what's very odd?"
Edith and Agnes shrugged. "This dog just talked to me." Margo said. Agnes gasped. "That's awesome!" She yelled. "More like strange." Edith said. "I know. Dogs don't talk." Margo said.
"What do we do?" Agnes asked. "Should we keep it?" Edith asked. "I think we should wait for Mom and Dad to come home." Margo said. "Okay." Edith said.
Margo closed the door and GIR left the house. He went back to Zim's base.
Quickly, GIR took his disguise off and jumped on the couch. He started watching The Scary Monkey Show.
Zim came up from his base. "GIR, what are you doing?" He asked. "I'm watching The Scary Monkey Show." GIR said. "That monkey!" Zim yelled.
"I also met Margo, Edith, and Agnes." GIR said. "Who are they?" Zim asked. "Three nice humans that I met when I walked around." GIR said.
"GIR! Humans are our enemies and you weren't supposed to leave the house!" Zim yelled. "But they're nice." GIR said.
"I don't care how nice they are, they are our enemies!" Zim yelled. "Aw." GIR said.
An hour later, Gru and Lucy walked into their house. "Girls, we're home." Gru said. The girls walked over to their mother and father.
"Hey Dad, one hour ago, Edith, Agnes, and I saw a dog." Margo said. "A dog?" Gru asked. "Yeah. He was so cute." Agnes said.
"Was it green?" Lucy asked. "Yes." Edith said. Gru gasped. "I know that green dog." Lucy said. "Really?" Agnes asked. "Yes. His name is GIR and he's…."
"Pure evil!" Gru interrupted. "What?" Agnes asked. "That's not even close to what I was going to say." Lucy said. "I was going to say that GIR was so cute."
"I wish we can see him again." Agnes said. Margo saw something white on the floor. It looked like paper. She picked it up and read it. "Hey guys, check this out." Margo said.
Gru and Lucy looked at the piece of paper. "It's a phone number." Lucy said. "I'll be right back. I've got to upgrade a security camera." Gru said and he walked away.
Edith took the paper from Margo, walked over to the phone and called that number.
The phone rang in Zim's base. Zim was doing some work, so GIR picked the phone up. "Hello." He said. "Hello. Who is this?" Lucy asked. "This is GIR." GIR said.
Lucy gasped. "GIR! Hey. I'm Lucy Wilde." Lucy said. "Hi." GIR said.
"My daughters really like you. Do you want to come over for dinner tonight?" Lucy asked. "Yes." GIR said.
"Okay. I'll see you in a few minutes." Lucy said. "Yep. Bye." GIR said and he hung up. He put his disguise on and left the house again.
Zim heard the door close. "GIR, what was that?" He asked. He looked around and he didn't see his robot. "GIR?"
GIR was heading off to Gru's house. He knocked on the door. Lucy opened the door and she let GIR in.
The girls saw GIR. "Yes!" Edith yelled. "GIR!" Agnes yelled. Edith put some music on and GIR started dancing. Margo took her phone out and started recording GIR.
Zim ran around his base. He couldn't find GIR, so he grabbed his disguise, put it on, and left the house. He was going to look for GIR.
But what he didn't know was that Dib was following him. "Zim! Where is he going?" Dib asked. He was talking to himself.
Zim went to Gru's house and he knocked on the door. Lucy opened the door. "Oh hello." She said.
She did not know that it was Zim. She thought this guy was someone else. Lucy and Gru met Zim when he wasn't in disguise.
"I am here for GIR." Zim said. "You know GIR?" Lucy asked. "Filthy human, I am Zim!" Zim yelled. "Hmm. That's interesting." Lucy said.
"What?" Zim asked. "Earlier today, my husband and I met an irken named Zim." Lucy said. Zim sighed. "I am Zim!" He yelled.
Meanwhile, Dib walked around. He didn't know that Zim was at Gru's house.
Pretty soon, he was in a dark corner. "This looks like a safe spot to track Zim." He said. Then he bumped into a woman in a red dress. He bumped into Scarlet Overkill.
"Oops. Sorry." Dib said. "What are you doing here? How did you know about our secret hideout and who the heck are you?" Scarlet asked.
Vector, El Macho, Herb, Meena, and Antonio looked at their leader talking to a boy. "Yeah. Who is this kid?" Vector asked.
"I'm Dib. Who the heck are you guys?" Dib asked. Scarlet looked at her team. "Huddle up." She said.
The villains talked to each other.
"What should we do? Should we tell him?" Scarlet asked. "Yeah." Herb said. "What? No way! He might be on Gru's side and expose us!" Vector yelled. "We don't know for sure. Did he talk about a little boy with a big head?" El Macho asked.
"My head's not that big!" Dib yelled. Scarlet walked over to Dib. "Look kid, I'm going to say this once. Get out of secret location!" Scarlet yelled.
"Fine. You guys are freaks too." Dib said and he left.
"Weirdo." Vector said. "Now let's get our main target." Scarlet said. The other villains groaned.
Zim walked into Gru's house. There, he saw the girls and GIR dancing. Zim shook his head. "GIR!"
GIR looked at his master. "Hi master." GIR said. "What are you doing?" Zim asked. "I have friends." GIR said.
"Let's go GIR. We're leaving." Zim said. "Aw, but I like it here." GIR said. "Let's go GIR!" Zim yelled. "No wait, can we just stay for dinner?" GIR asked. "No!" Zim yelled.
GIR looked at the girls. Agnes used her little puppy dog eyes. "Aw. But look at Agnes." GIR said. "Fine." Zim said. GIR squealed with joy.
Lucy was cooking and she put the dinner out for the girls, Zim, and GIR.
The girls and GIR were eating, Zim on the other hand was struggling. He can't eat human food without getting sick.
Zim poked at the human food. "You want me to eat it?" GIR asked. "Fine." Zim said. GIR started eating Zim's food.
"GIR, what are you doing?" Lucy asked. "Oh my master…."
"GIR!" Zim screamed. "What?" GIR asked. "I'm just not that hungry." Zim said. "But I thought you can't…"
"Shush!" Zim yelled. "Okay Zim, but we're having pie for dessert." Lucy said.
"Pie." GIR said. "No GIR. We're leaving." Zim said. "Master, can we stay for pie?" GIR asked. "GIR." Zim said.
"Please?" GIR asked. "No!" Zim yelled.
Gru walked over. "So, is this the alien that we saw earlier?" He asked.
"I think so." Lucy explained.
Zim grabbed GIR and they both left. "Oh great." Gru said. "So much for telling Silas and Valerie."
Zim and GIR went back to their base. "You've got to be careful GIR! We almost got exposed!" Zim yelled.
"Oh." GIR said. "Next time we see them, I will kidnap them and we'll tell the tallest everything!" Zim yelled. "Yay!" GIR yelled. "I am Zim!" Zim screamed.
Gru and Lucy cleaned the kitchen. "Aw. I thought they were our friends." Agnes said sadly. Edith moved her chair to Agnes. "Oh well."
"We're still going to find them right?" Gru asked. "They seem harmless. Let's tell Valerie and Silas that." Lucy said. "Alright." Gru said and he moved on.
