The Ostheimer badger with head straight is one of 3 badgers currently made by Ostheimer, which makes it possible to have a badger 'family'. If one were to purchase only one badger however, the small 'baby' badger would be fine for a forest creatures collection if one were partial to the smaller figures, and a little cost-savings for the smaller figures; however, in real life badgers in Europe can be quite large, so the adult size badger would be more representative; the adult North American badger is a little smaller than the European badger (if such thoughts entered one's head as a matter of import).
The badger head down looks like it is snuffling in the ground more, a typical scene for this burrowing insect and grub-eating creature. The badger with head up looks more as though it ready for conversation with another animal.
Please note that the badger head down is part of the Ostheimer forest set with diorama, in case one were interested to purchase that set.
