(at around 4 mins) Top Cat's hat changes from purple to red.
When Dibble encounters Charlie, the taxi driver, Charlie is in the cab. Two shots later, he is out of the cab. In the shot after that, Dibble is in the cab and then drives away. We do not see or hear either of them getting in or out of the cab.
When the gang first gets into Dibble's car, Choo Choo and Spook are sitting in the back with Benny. Later, Fancy is in Chooch's place. After that, Fancy is in Spook's place and Chooch is in Fancy's place.
When the gang is in Dibble's car, in one shot, Benny's feet are green, the same color as Spook. Later in the same shot, when TC starts talking, Benny's feet are back to blue.
Dibble's fare for using the cab is $57.89, as shown on the cash thing, but when Dibble reads it, he says, "$57.85."
