Pooh! A Pooh area would be very cool. The laff things could be hunny pots.
I know somebody suggeested a Wild West themed area with tumbleweeds blowing around and cacti (I think) for the laff points for Goofy instead of his current place in Daisy's Garden. I think that'd be great!
I (I know this has been suggested too) wouldn't mind seeing an entire area based around Chip N Dale. It could be a woodland glade or a (maybe?) tree. The laff point thingies could be acorns.
It doesn't look like they're going to do areas based upon the more recent characters yet, but I'd love to see something like the city from Aladdin, or the savannah from The Lion King.
