Avatar: TLAthose are also targeting an older audience, teens. I don't know gumball I guess but gravity falls is not really young kid appropriate.
Gravity Falls
Gumball
Old spongebob wasnt the worst.
My son watches Octonauts and that isn't as obnoxiously dumb.
octonauts is pretty bad too but that is targeting 3-6. my almost seven year old has outgrown it at least.
