Garfield's Fun Fest is the second Straight-to-DVD film of the Garfield franchise.
Garfield is reminded several times that Fun Fest is coming up. Garfield isn't worried, and believes he'll win again, because he won the Fun Fest 29 times, and the 30th Annual Fun Fest is to come on Tuesdat Night. However, Arlene is tired of the same old routine she is always on with Garfield, and this time, she wants Tango-Dancing. Later, a mysterious stranger named Ramone comes, and he is introduced a cheesy-accent Mexican cat. However, after Garfield leaves Arlene, he realizes that he has lost all his hope, and he thinks he has no humor left. With Odie and the help of a storybook (later revealed to be a fictional story), they travel to the Mysterious Forest of Humor to drink the legendary funny water, which was the dedication and the infamous praising of the creator of humor technology, Freddy Frog. Freddy helps Garfield become explained that funny water does not exist, and that he had just had to believe in himself, and there was no need to come of the forest with Odie. Taking back a wooden airplane to fly back to the Comic Studios, they crash into the floor, and see Ramone hosting as the MC, and now he has made Arlene suffer a nausecous-dizzy spin in the Tango Dance. Garfield puts himself forward and puts on the Mexican- Dancing Tango costume, and battles Ramone. Ramone and Garfield battle each other in the Fun Fest, and Ramone is revealed as a cyborg. However, Garfield finally turns the tables on the cyborg imposter by pulling his head off, and it is now revealed that it was Nermal controling Ramone all along. Garfield is named the Winner, and continues his dancing of tango with Arlene, continuing his legend of his success in his own life and Cartoon World. Nermal tries to come up with another plan to win next year's Fun Fest, but Odie is skeptical. Garfield and Arlene kiss and the film ends with Freddy flying his wooden airplane over the Comic Studios.
