Other mistake: During the dinner party scene, Carl is going gopher hunting. The shot of him approaching the tree shows it's daylight in the background, when the previous shot showed it very very dark out.
Other mistake: When Kit Mambo prepares to catch up with Renè Fromage, she first overtakes two guys (the raccoon and the bighorn sheep) on 'third and fourth positions' - as announced by Barbara Warbler, then she passes the sheep and the camel before she catches up with Renè. This would place her first competitors on positions five and four, instead of three and four.
Other mistake: When Tommy tries splashing Rosa during their match she hits the ring mat with her chest and stomach yet seconds later she's somehow knocked out. I never saw her head hit after multiple viewings of that scene.
