Beetlejuice (animation)/WMG
Donny Juice was sent to Neither Neither Land at one point.
That's the reason he's so saccharine and sweet all the time. My guess is that he used to be a lot like his brother Beetlejuice, but eventually went one step too far with some stunt or another. One trip to the Jack In The Box later, and he's the Mister Rogers clone we all know and loathe. That's why Beetlejuice is so utterly terrified of Neither Neither Land. He's seen firsthand what it can do to someone.
Cartoon!Beetlejuice is Lydia's Fairy Godparent
He has magic no other ghost seem to have, he's mostly focused on helping Lydia and making her happy, he has the ability to teleport and shapeshift while still having his prime colors own and usually flot. he's either pretending to be a ghost because he's afraid that Lydia thinks faries are lame, or he's suffering from some kind of amnesia
The show is a Prequel to the movie. Lydia and BJ just suffer from Laser-Guided Amnesia
Lydia looks a lot younger in the show then in the movie, and we've already seen that without BJ, Lydia will become very sad and depressed. It's not much of a stretch that without Lydia, BJ would become a bigger Jerkass. Sometime after the show ended, both Lydia and Beetlejuice got Laser-Guided Amnesia somehow and never met until Lydia and her parents moved to the Maitlands' house, where they met again (BJ now calling himself Betelgeuse), but they changed so much in the 4 years they never met, that they could never become friends again
