Just a natural hazard of being a bear. Ogres steal their action points, they get blinded, or feared, or have no path to enemy = sleepy sleepy bears.

I think it's a minor issue. They should have used a different mechanism for determining hibernation. Maybe make it a special ability that you activate.

Actually, that'd make them kinda good early game. Activated ability that fully heals the current bear, but spends their turn. I could see it, especially for Polar bears.

Come to think of it, WotN actually did a lot for bears. Battle Maiden raise their morale, the Honey artifact grows their numbers... not to mention they are one of the few neutral options early in the game.

Ooh! What happens to Honey blocks when they run out of honey?

Oh bother, Christopher Robin. We are out of ... HUNNEY!

Aw, crap. Pooh bear frightens me to death.
