The new bear has an all new quest line, and Science Bear has 5 more quests as well. I'll try to add some new ones to Polar Bear's pool of quests to mix things up too.
Bee Swarm update releasing on Friday, will include some new bees, new items, and a new bear! Also, just 6 more days left to purchase Bear Bee before it becomes unobtainable (existing Bear Bees are permanent).
