Zimmy is an inva-der that no one understands!
Tallest Red and Purple always giving him commands:

Purple: "Fries, twerp!"

The planet's doom is coming soon,
'Twill soon rain down on thee!
It's the guy from Planet Irk
(his disguise could use some work) -

In-vader, Irken Invader!
Dib: "They're com-ing!"
Zim: "You're doomed, human thing!"
In-vader, Irken Invader!
Mongoose dog, Pizza Hog, back pod, green bod!

With the Invader called Zim!

Dib: "Not if I can help it!"

Gaz: "Shut up."
