When Choo Choo reveals that the man running the pizza shop is actually Officer Dibble's cousin, in one shot, TC is holding Choo Choo. In the next shot, he is not.
In one scene, Dibble is talking to TC. In one shot, the garbage can lid is on TC's head. Two shots later, it isn't. We do not see or hear TC taking it off.
In one scene, Choo Choo's tail has vanished.
