LarryBoy: The Cartoon Adventures (also known as simply LarryBoy) is a cartoon adaptation to Larry-Boy and the third show created by Big Idea.
The cartoon series starring everyone's favorite plunger-headed hero started a few years after the production of either the first or second Larry-Boy videos were completed, when the staff were asked on doing a series on the character. But Phil Vischer stated that it would've been too hard due to the production process of their feature film at the time. Then someone suggested to Phil that could make it in a style of a comic book; cartoon style. Animator Tom Bancroft who just joined the company worked on the new series, making it a "cartoony" done in flash animation.
The first episode of the series was released during March 16, 2002, selling to various Christian bookstores and retailers across the country. However, the reception was mixed at the time. According to Phil in his blog, fans and parents complained that it looked cheap and it looked like something similar to "Powerpuff Girls" that they can watch on cable television instead. Tim Hodge stated in the Bad Apple commentary it was somewhat an experiment they tried out, but didn't become what they wanted.
The series lasted for four episodes total, with the last one coming out around June 10, 2003. It is unknown why the series was cancelled, though it is possible it was due to Big Idea moving to Franklin and because of the reception everyone had towards the series at the time.
