Odie becomes a monster-dog in the middle of the night and eats a lasagna that was for for Jon and Liz. Jon thinks that Garfield is responsible, and blames him.
Garfield and Odie get taken to another land through a magic mirror where Neferkitty (voiced by Susan Silo) and her Egyptian colony of cats live, planning their revenge on humans.
Garfield and Odie are mistakenly accused of stealing barbecued ribs (really stolen by neighborhood pets) when they run away from Jon's twin girl cousins.
When an Alien stops at a Super-Market in earth, Garfield mistakenly enters his Space Ship and travels through different planets but it becomes hard for him to survive. The space ship and the alien are very similar to Doc Brown and the Flying DeLorean Time Machine from Back to the Future.
Your favorite lazy, fat cat is at it again. Garfield, Odie, Jon and the rest of the gang are back for more funny misadventures. Whether he's scarfing down lasagna or tricking Nermal the kitten, Garfield is guaranteed to crack you up. But remember: He hates Mondays!
