Continuity mistake: When Garzooka goes to Garfield's house, he pounds on the door and it appears as big as him. But after he breaks the door open, the doorway is thinner. (00:17:05)
Continuity mistake: When Garfield unscrambles the monster, the moscram is on super-scramble mode, but when he unscrambles Pet Force super-scramble mode is turned off. Even though there was time to turn it off, you can see Garfield's hands almost the whole time. One of them is holding the moscram and the other one is down on his side. (01:05:55)
Continuity mistake: After Garfield says, "Hey, Odie, got tongue?", he makes Odie wrap his stun-tongue around the monster and then ties the tongue. But later Odie's tongue goes back in his mouth, even though it was stuck to the monster. (01:05:25)
Continuity mistake: Professor Wally in the background looking at Garzooka when Betty knocks him down. However, when the two Jons say, "Lookin' good" Professor Wally is now looking at Garfield. (01:07:50)
