Templeton

Templeton is a green-skinned rat who has been left to fend for himself within sewer society. Wishing to return to city life and escape his underground tragedy, he must navigate 30 screens of underwater pipes while avoiding hostile starfish, clams, fish rubbish bins, and sea anemones.

Templeton has limited oxygen, and must find air bubbles to catch his breath. He also picks up turnstile passes that allow him to pass turnstiles on his adventure. The starfish will only move if the player stands directly above or below it, and the garbage can can only be passed when it is immobile and closed. The player starts with five lives, and loses one if Templeton touches an enemy or runs out of air.
