Well, looks matching with the previous figures, but in a few weeks we'll know for sure.
Checked on what you asked about the mystery dimension: I got at least one pack of every franchise and all the gold bricks for year one, including the mystery dimension. So I started it again, but I just go back to the desk with the waves of enemies as usual and after I beat them all a bit of the original trailer where Gandalf, Wyldstyle and Batman enter our world. Nothing special or new.
Unikitty couldn't either hold anything, right? I don't have her, yet. I think and i'm not sure that the adventure world would at least be in the mansion and maybe there is a portal to go the miniature city where Beetlejuice normal lives and a portal the underworld?
I don't have Unitkitty either, but like Scooby she's an animal and doesn't really have an items with her in the movie. That's what I have been wondering about: Which parts of the movie (or animated series?) will they use for the adventure world. The miniature city and the underworld but be great to have!
Never knew that there was an animated serie about Beetlejuice. Does he has in the series this ''special'' hands that he has now? It's hard for me to say if this character is based on the movie or on the animated serie, could you see on which one it's based on?
Oh dear, it's so long ago that I watched that series, had to check back on youtube... Here the original intro
he has 'normal' hands, that look a little odd. I think the figure resembles the movie a little more, but the animated version was based on the the actor, too. There's some resemblance. Just hit me: Wonder if the Adventure world will be more animated like Scooby Do or more realistic like the Gremlins
About the Adventure world: I think that depends on if it's based on the movie or animated version. I hope so that he is based on the movie character than he is based on the animated version. Now we have to wait if there come more leaked pictures or that they official give some pictures. With Vehicles from Beetlejuice en that Powerpuff Girl.
