Cats (players) must vie in an effort to awaken a large serpent that protects their dreams. Otherwise, they (cats) will be stuck in sleep terror.
Players use snakes to entice cats at sheep stationed on or within various structures with the intent of feeding them to the sharks below, which then turn into little friendly fish, so players advance through the game with new types of cats that become available. Special abilities are activated by the player if their cats get a fish that was once a shark.
Activity is to wake up sleeping cat with snake with these hungry sharks below, as the objective is to awaken dreaming cat and escape the sleep terror.
