A special one-shot written and illustrated by Sarah Andersen (Sarah's Scribbles)! When GIR brings home a flea-ridden stray cat, ZIM is furious-until he finds out what the cat does to Dib. Dib's sneezing and covered in hives-could the magical powers of this "cat" be harnessed and turned against all of mankind? Could the earth FINALLY be ZIM's?
