Pickle & Peanut - Season 2 Episode 8 Funwagon

Pickle and Peanut are forced by Laser to wash his prized sports car "Funwagon" after they unintentionally splash it with mud. However, they accidentally hose the car down with some toxic ooze from a nearby truck instead of water, and as a result, the ooze grants Funwagon mutated sentience and a freakish face, which ultimately causes a horrified Laser to disown the vehicle. The two befriend Funwagon and decide to "raise it" as their own, until Laser has a "change of heart" and decides to take back Funwagon in order to enter it into a demolition derby for a $10,000 cash prize, which causes Pickle and Peanut to go after Laser in the truck that contained the toxic ooze to begin with in order to rescue Funwagon from being demolished.
