Doug's Fat Cat / Doug and Patti P.I. - S3-E1
Other mistake: Doug's Fat Cat: When Doug imagines himself reporting Stinky on the phone, when Stinky is chasing Porkchop, her tail is layered over the wall in front of her. (00:02:15)
Doug's Fat Cat / Doug and Patti P.I. - S3-E1
Other mistake: Doug's Fat Cat: After Stinky is revealed to be a mother, there is a shot of two of the kittens playing with each other. The two kittens keep turning into the opposite kitten repeatedly (you can tell because they keep flashing opposite colors), indicating that the animation is simply looped over and over. (00:11:14)
Doug's Servitude / Doug Rocks the House - S3-E2
Other mistake: Doug Rocks the House: When Doug tries to talk to Patti at her locker, after he gives the rock and marker back to the kid beside him, the kid's glasses lose their colour for one frame. (00:18:00)
Doug and the Weird Kids / Doug's Behind The Wheel - S3-E6
Other mistake: Doug's Behind the Wheel: When Judy parallel parks the car, as Doug tells her that she just parallel parked, he sticks his hand right through her seatbelt to touch her shoulder. (00:21:51)
Doug and the Yard of Doom / Doug's Garage Band - S3-E12
Other mistake: After the "Think Big" number, Doug writes an idea down in his journal. There are a brief couple of shots where the edge of the animation cel is visible. It is a white line that disappears.
Doug's Great Beet War / Doug's Magic Act - S3-E13
Other mistake: Doug's Magic Act: When all the items fall out of Doug's mirror cabinet, a purple bottle falls out last, and it is incorrectly layered behind the other items on the floor. (00:17:39)
