Korilakkuma met Chairoikoguma while on vacation with Rilakkuma and Kiiroitori in the "Honey Forest". It has a bushy chest and when it opens it's mouth reveals fangs! It has bear prints on the soles of each foot and its body smells like sweet honey. Chairoikoguma, (or Kogumachan) is usually seen walking on all fours, even if he can stand up straight like his partners. The four friends all climb the trees together, play tag, and sometimes tend to fight over honey.
