Hay guise, I has some predictions:
- Many of the old enemies will come back and be possessed by the lich including: Memow, Ricardio, Tiffany (probably not but lol xD), THE SNAIL, possibly those ghost friends of Marceline (too lazy to check their names), Donny (he’s not really “evil” but who knows?), Sir Slicer (he really needs another apperance).
- Billy will return and help F and J deafeat the lich.
- The Lich will hold all the princesses of Ooo hostage.
I will add more if I think of anything else.
Comment some predictions you have :D
