Human 1 Ninja / X Druid with Able Learner. Start with decent Int (say 14), you get 7 skill points per level in total (2 Int + 1 Human + 4 Druid). Enough to max out Concentration, Spellcraft, Knowledge (Nature), Search, Disable and 2other skills of your choice.

Ninja is used as it nets you trapfinding, and lets you add your Wis bonus to AC when unarmored, like when you wildshape for instance. You won't have sneak attack (and sudden strike is a poor alternative), but that hardly matters when you can transform into a bear and maul your enemies anyway.

If you don't want to completely overshadow the rest of the party with a Ninja-Druid, Spirit Shaman can also work (since it also gets 4 skill points per level). But the MAD is terribad since it needs high Wis and Cha on top of everything else.
