That's what i'm screamin'

Scooby and the gang have worn the same outfits for 45 years. Flintstones and Jetsons over 50 years. We won't even go into Yogi's outfits.

It's in the budget of nearly every animation series so the character sketches can be used over and over again.

"Cartoon humor" It's just a cartoon like gumball and darwin, they looked the same for almost most of their show, but they are good at breaking the 4th wall
Just like pinkie pie XD
