Ok, I'm actually curious so how are you gonna change Hat Kid's (aka Lydia's) role in your Beetlejuice AU? What's her reason for summoning Snatchjuice?
(For future reference, I call Snatcher “BetelSnatch” in this AU! Not Snatcherjuice, since that sounds a bit…weird. But no worries, just thought I’d clarify!)
Well, for one, Hat Kid is still her normal self! Or, she’s herself but a bit gloomier? (Since moving would probably make her a bit home sick) I might just go with both? But as for the role thing, what I mean is she won’t be a teenager. If you’ve seen the movie, you’ll know how Lydia acts and…well, I don’t think that would mix too well with Hat Kid. Since she’s a child and all, I prefer she stays the way she is in canon game!
Her main reason for summoning BetelSnatch though, later on in the story, is that she wants to be friends with him! That, and she asks BetelSnatch to “help her become a ghost” so she can be better friends Conductor and Grooves! Eventually though, the story plays out just like the movie and Hat Kid needs help saving her friends. But in return…BetelSnatch requires something from her.
BetelSnatch whips up a contract that Hat Kid has to sign in order for him to get out of the Nether World for good. And that contract states that they will literally be “Best Friends Forever” once she signs it, leaving Hat Kid in BetelSnatch’s place.
Hope that clears things up! ^^
