The film was released on DVD in the United States on August 5, 2008, by 20th Century Fox Home Entertainment, and was pre-sold internationally by sales representative Velvet Octopus.

Sometime after the events of the first film, Garfield is reading a book about the origins of Freddy Frog, his pond, and the beginning of humor to Odie.

Garfield attempts to perform a new act that is done by himself, but he bombs it due to Ramone's heckling, and his ego is deflated.

When the duo opens it, they see that it's a map that leads to Freddie Frog's (from the opening scene) pond; Garfield plans to travel to the pond and drink the water in order to be funny and win the show, hoping to impress Arlene.

While Arlene is disappointed that Garfield was gone and worried that he is jealous and hurt, Ramone manages to win over the audience and judges with his quips and accent.

As the crowd cheers for Garfield's performance, they boo Nermal and force him to shamefully get off the stage, disqualifying him.

Garfield's Fun Fest was released on DVD on August 5, 2008, by 20th Century Fox Home Entertainment.

Its most profitable market was Brazil, where the film generated $729,560 in revenue and opened at sixth place with $219,801.

[6] Paul Mavis of DVD Talk said in his review: "Maybe the problem is that Garfield creator Jim Davis, who wrote this movie, can't translate his humor into an 80 minute film.

The obvious video-game structuring of the scenes is to be expected, I guess, in these days of rampant, voracious synergy, but that doesn't make the film any more palatable.

Following the success of Fun Fest, a sequel to the film, titled Garfield's Pet Force, was released on June 16, 2009.
