Chocobear

Chocobear will gain a 50% boost to all campaigns if you feed it chocolate or do a food campaign with it. The boost is stored as hours, and you gain 3 hours per chocolate fed and 1 hour per 1 hour in food campaigns. Chocobear will not use its stored bonus hours if it is in food campaign, or the target in a growth campaign. You need to store at least 200 hours to evolve Chocobear and they are consumed on evolving. You can see your current banked bonus hours in Chocobear's tooltip.

Token Upgrade
You can use a pet token to increases its boost to all campaigns to 75% (up from 50%) if you feed it chocolate or do food campaigns with it.
