As the years pass, not much changed. Dib got taller while his attire changed dramatically.
He now wore loose fitting blue jeans and he had lost the trench coat, while his t-shirt changed into an evil looking frown face.

Zim on the other hand, remained the same. He had grown at least 1-2 inches over his years on Earth.

No one seemed to be bothered by his small size, because they assumed he was a midget with anger problems.

As horrible as it might seem, Zim and Dib were in almost every class, counting gym.
Barging into the gym room, Zim quickly burst into the boy's locker room and changed as he always did before anyone could see him change.

Scrambling over to the cushioned wall, Zim waited as everybody taller than him started to line up against the same wall.

"Zim, what have I told you about wearing gloves!" Hollered the overweight gym teacher.
"I told you it's a religion," Smiled Zim "see, she gets to wear that head thingy!" accused Zim as he pointed his gloved claw at a girl who was coming out of the locker room.

"Seems like your hiding something," snickered the older Dib. Sticking out his snake like tongue at Dib, Zim crossed his arms against his hideous gym shirt as he kicked Dib in the shin.

"Hey, what's that" began the gym teacher, "I tell you everyday, No Boots!" "I can wear them if I want," growled Zim.
"No you can't, cause for the next two weeks we are swimming," sighed the teacher.

Feeling the life draining from within him, Zim looked over at an overexcited Dib.
