Here are the animation errors of Crazy Cat.
When the anvil falls on Crazy Cat's foot, Crazy Cat's head is sightly off-center. And when he screams "OWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW!!!!!!!!!!!!!!!!!!!!!" his eyes turn orange.
While Lucy the baby bumblebee is singing pop music, Paul's third eye disappears, and when Lucy stops, Paul's third eye reappears.
Lucy's Big Party!
Paul says he is looking for soda but he instead gets Mountain Dew Throwback.
During the pool party, when the Omation O jumps into the pool, he turns purple.
When Paul says he is going to JellyfishJam38's house to get ten VHS cassettes, the Paulmobile's fuel tank is off-model.
When Paul puts the first cassette, The Michael Rosen Rap, in the video cassette player, the VHS is off model.
As Crazy Cat says, "No chewing gum in your Paulmobile!" in the 4th VHS, his nose is missing.
The Failed Plane Ride
Before the plane crashes, Crazy Cat shouts "Mayday! Mayday!", however, the closed captioning says that Paul said it.
