The Hibernation Comb includes a number of pods grouped into sectors; each sector offers a small endgame scoring bonus for having the most tokens.

When a strength-4 worker would increase its strength (e.g., via being bumped or retrieved), it must hibernate. Return that worker to the general supply. Then, place a hibernation token representing that worker in any vacant pod available for your player count and gain the benefit printed on the pod.

Several pods offer the benefit of refreshing a tile row within the Advance action. If you fill such a pod, you must discard all tiles in the indicated row (farm, recruit, development) and replace them from the corresponding stack.
