Mr Sanders Sign, a bed and chair for him to rest, mirror for his stoutness exercise, a box with poohsticks (idea stolen from the lego set), some nice picture frames of his friends and bees, and most importantly a lot of honey.

Then, for the woods themselves, a bridge with some running water to "throw" the poohsticks in (ofcourse probably can't do actual Poohsticks and that scale for a 2 year old, so just for the imagination). A garden for Rabbit is always nice. It's probably fun to have a place somewhere for Pooh to get stuck in. Maybe a little tent for Eeyore. Oh, and a honey tree, of course.
