Before Handy Manny premiered, there was a test pilot screened to the creator of the show in 2003/2004. It featured Manny and his tool friends having fun, whether it's building stuff, saving an environment, or fixing a bowling lane, it's Manny to the Rescue!
In 2004, an 11-minute pilot was created for the series. Unlike the main series, which was animated by Two Presidents Productions, the pilot was animated by DKP Studios (now known as Jam Filled Toronto). The pilot also used standard 3-D animation instead of cel-shading, and had more simplistic sets. The only video footage of this pilot can be seen in a demo reel from DKP Studios' official website. Aside from a resume of CG artist Kyran Kelly, who directed the pilot, little information can be found.
