Bookworms

Every Campus in the game will frequently be visited by Bookworms. These visitors will appear in a puff of smoke, then submerging and emerging twice more before disappearing. If the player can click on a Bookworm before it submerges a third time, it will be caught, and grant a small reward. They do not observe a paused game, and will carry on as they wish while all the Pointians are frozen.

The following table shows the six types of Bookworms that will appear, arranged in order of rarity.
