Kenny kidnapped Sally the rat (Spenny's rat). Spenny retaliated by stealing his valuable vinyl records, which angered Kenny into "kidnapping" Spenny's mother, who he exchanged for his records. Kenny then used a large capybara, claiming it was a "South American Jungle Rat". However, during the race, the carybara stopped half-way down the track and didn't run further. While Kenny was trying to encourage the animal to run, Spenny's rat ran off the track. Spencer picked it up and put it back at the start of the track, thus violating his own interference rule
