Garfield and the Wicked Wizard — Michael Teitelbaum

GARFIELD's off to see the wizard!
This has to be the weirdest day of Garfield's life. When Jon takes Garfield and Odie to a medieval fair, the strangest thing happens: Garfield and Odie are magically transported back to real medieval times!

There they meet Hairball, a cat no bigger than a mouse. Hairball tells them an evil wizard has cast a spell on him and has kidnapped the king. Hairball knows how Garfield and Odie can get back to the present, but he won't tell them unless they help him rescue the king.

Can Garfield and Odie break the wizard's spell and find their way home?
