This is blue bear. This guy is super shy. which means everyone in smart Vally barely sees him.

and since he's half polar bear, he loves the cold winter. Which means he never hibernates. even though he does sleep sometimes.

Also, and you might not know this, Blue bear also serves as the wolf kings assistant. Meaning that it's his job to make the wolf king very happy. and sometimes he pals around with Zolt and his two brothers.
