Dude, I think BoohBah is the trippiest thing ever aired and should definately be adapted into an adult show. I already love it!
courage the cowardly dog is just plain creepy sometimes. but in a good way. just the animation and the strange music make it the weirdest cartoon on cn.
For me it's "ginban kaleidoscope" because the story is all about the girl whose body was possesed by a boy spirit...The spirit see what the girls see and it's crazy because she was able to change her clothes blind folded... DVD CORNER AMAZING TV SHOWS
Courage the Cowardly Dog is a really strange show. It is pretty creepy a lot of the time. It can be a good watch.
There is a show on Nick Jr called Yo Gabba Gabba. It can get pretty trippy. Rocko's Modern Life is pretty trippy too.
Many were already said (some of my favs are cow&chicken and courage the cowardly dog, on boobah is the trippiest shit ever) Two cartoons that are awsome are Ed, Edd, and eddy and The grim adventures of billy and Mandy. May not be very "trippy" but awsome and probally the best shows ever stoned.
SpongeBob Squarepants. I watched it with a 4 year old the other day and actually enjoyed it. Very unique animation. x
There is a really trippy Anime called "Gantz" (don't watch with kids). I couldn't watch it the titles were so disgusting, but it looks well made.
You haven't seen a trippy cartoon until you've seen Rene Laloux's movies; Fantastic Planet, Gandahar, all good stuff
spongebob ... watched it and all i can say is that i love this cartoon the mindfucking ideas and so on...
holy shit i forgot. i change my vote to perfect hair forever. id say something like home movies or metalocalypse or lucy the daughter of the devil or saul and the molemen or that new friday night horror theatre show because these are all pretty random and hilarious but nothing even touches PHF.
