Continuity mistake: Spence and Dennis arrive at Dinkie's in the doorless car they stole from the villains. In the first shot there's no skater waiter in sight, in the second one darts by the right car door hole. (00:35:00)

Continuity mistake: Turnip is playing (and hamming) with a plush toy dog that didn't get in the car during the crash nor he is holding it in the wider shot. (00:28:00)
Continuity mistake: In the shot when the baddies crash through the toy stand, the hole in their radiator grill is patched up, unlike the rest of the scene. (00:27:55)
