Zim woke up, put his disguise on, and ran to the door, but Skoodge surprised him.

"Hey Zim!" he yelled.

Zim screamed and fell down. "Really?"

"Oops. Sorry."

"It's alright." Zim said and he got up from the floor.

"Where are you off to?"

"I'm going to skool."

"Oh. I wish I went to your skool."

"Why would you want to go to my skool? There are already two aliens going to skool. The last thing Dib needs is three." Zim explained.

"Hey how is Dib? Is his arm alright?" Skoodge asked.

"Yeah. His cast is off." Zim said.

"Good."

"Well later." Zim left the house.

Skoodge sat down on the couch and stared at the TV. He sighed. Gir walked over. "What's wrong Skoodge?" he asked.

"I want to go to Zim's skool."

"Then go to my master's skool."

"He didn't want me to." Skoodge explained.

"Let me tell you something. My master always tells me not to do something, but deep down, he actually wants me to do it."

"Really?" Skoodge asked.

"Uh huh."

"Thanks Gir." Skoodge put his human mask on and hat. Then he left.

At Skool, Dib and Zim were talking about Skoodge.

"So he really wanted to go to skool?" Dib asked.

"Yes." Zim replied.

Dib chuckled. "I'd love to see him try to keep his identity a secret."

"I'm just glad he's not here."

When they got to Ms. Bitters class, Ms. Bitters was yelling to someone on the phone. "No! Not another one!" she yelled.

Zim couldn't help, but listen. "Huh?"

"We already have Tak. We do not need another one!" Ms. Bitters yelled.

Zim looked at Dib. "Another what?" he asked to the boy.

"Another student?" Dib asked. Zim gulped. He didn't want it to be Skoodge.

Ms. Bitters hung up. "Alright! Class, a new student will join us. I am forced to introduce you all to a boy. Hi name is Skoodge."

Skoodge walked in. "Hey guys! My name is Invader...I mean Skoodge."

Dib giggled. "Yeah, he's not good at keeping secrets. He almost said invader."

"He did." Zim corrected.

"Oh."

"Skoodge! What are you doing here!? I told you not to go to skool!" Zim yelled.

"But Gir said you say a lot of things, but you mean the opposite." Skoodge explained.

Zim facepalmed. "Oh please don't tell me you actually believed him."

"I did."

"You are so gullible." Zim said. Dib kept laughing.

"So where do I sit?" Skoodge asked.

"Zita, move back on seat." Ms. Bitters ordered.

Zita did what she was told to and so did the other kids behind her. Skoodge sat behind Zim. "This is great Zim."

"Yeah. Real great. You cannot expose yourself."

"I didn't."

"Yeah right. The entire class heard you say your name was Invader." Dib reminded.

Skoodge saw that Dib was next to Zim. "Hey! How come you get to sit next to Zim? And don't say it's because you called dibs like when we went to the aquarium." Skoodge said.

"Are you seriously going to start with that again?" Dib asked. "Wait a minute. You went here before when Zim was a smeet."

"Yeah but that was I was filling in for Zim. Now I'm Skoodge."

"Just be quiet guys. I'm very nervous about this." Zim said.

Dib looked at Zim. "Zim, calm down. What can happen? Skoodge is so gullible. He'll believe in anything."

"See? That's the problem. He believes in everything! Wait until Ms. Bitters wants him to take his hat off."

Ms. Bitters saw Skoodge's hat. "Skoodge, there are no hats allowed in skool. Take it off!" she ordered.

"Okay." Skoodge was about to take his hat off until Zim stopped him.

"NO!" Then Zim told Ms. Bitters about Skoodge and his hat. "Ms. Bitters, Skoodge has a horrible hair style and he told me that he got made fun of in the last skool that he went to."

Ms. Bitter looked at Skoodge. "Is that true?" she asked.

"Yes! I mean, yes." Skoodge said sadly.

"Tomorrow, take the hat off."

"Sure thing."

Zim gasped. "Dib!"

"What?" Dib asked.

"If Skoodge takes that hat off, everyone will see his alien antenna."

"Yes! He'll be exposed!" Dib yelled. Everyone looked at him.

"Dib!" Zim yelled.

"Oops. Sorry. I mean, oh no." Dib said in an enthusiastic voice.

"We want to expose Tak, not Skoodge." Zim reminded.

"I know. It's just kind of funny." Dib started laughing until Zim stared at him.

"Sorry Zim."

In the cafeteria, Dib got some food on the skool lunch line and sat next to Zim. Zim took out his irken sandwich.

"Irken food?" Dib asked.

"Yep."

Skoodge got some food and walked over to Zim and Dib. He sat across from them, next to Gaz.

"So Skoodge is here?" Gaz asked.

"Afraid so." Zim answered.

"Why is he so nervous?"

Dib giggled. "Skoodge...Skoodge almost exposed himself!" he laughed.

Zim stared at Dib. "It's not funny."

"You're right. I'm sorry." Dib said.

Skoodge looked at the food and picked it up.

"No!" Zim screamed.

Skoodge looked at him. "What?"

"Do you know what human food does to you?" Zim asked.

"No."

"It hurts you!" Zim explained.

"Wrong."

"Okay. Fine. Let's see."

Dib looked at Skoodge, crossed his arms, and smiled. Skoodge took one bite of the food and started choking. Dib laughed.

Skoodge spit the food out and stared at Dib. Dib was laughing up a storm. Skoodge couldn't help, but tackle him.

Zim gasped. The other kids yelled the word fight.

"Why didn't you tell me that the human food hurts aliens!?" Skoodge asked.

"Hah! You admitted that you're an alien!" Dib yelled.

Skoodge stared at Dib.

"I thought you knew! Now get off me you filthy alien before you make me break my arm again!"

"You don't have a cast anymore!"

"But I'm supposed to rest my arm!"'

"Fight, fight, fight, fight!" The skool kids yelled.

Zim had to do something. He got up on the table. "ENOUGH! No one is fighting! Skoodge, Dib, stop arguing!" Zim screamed.

Tak was on the other side of the fight. She sat down at a table.

"Tak!" Skoodge knocked Dib down and ran over to her.

"Ow!" Dib yelled.

"Hey Tak."

"What do you want?" Tak asked.

"I want to sit next to you."

Dib saw Skoodge with Tak. "Oh no! Not again! You are not going to start flirting with Tak!"

"I like her." Skoodge explained.

"I'll expose you!" Dib yelled.

"Not a chance. Hey Tak. What's up?" Skoodge asked. Tak had no interest with Skoodge, so she sprayed him with a Poop can. Skoodge screamed.

"Get over here Skoodge before I expose you as an alien!" Dib called out.

"How about I expose you as a big head boy!?" Skoodge asked.

Zim ran over. "Not another word from you two!" he yelled. He took them back to his base. "Do you want to explain to me why you started fighting?"

"Well Dib here started laughing!" Skoodge yelled.

"Only because you can't keep your identity a secret! Zim's the worst invader and he knows how to keep a secret." Dib explained.

"Lies! I don't. You knew that I was an alien as soon as I went into Ms. Bitters class." Zim said.

"But you're better than what Skoodge did!"

"And then you got annoyed at me!" Skoodge yelled.

"That's because you were hanging out with Tak! I told you! We do not hang out with her!" Dib yelled.

"I'm sorry. I won't do it again. So, can I go to skool again tomorrow?"

"Zim?" Dib asked.

"Alright, but don't ruin the plan." Zim said.

"No problem." Skoodge said.
