It’s an imaginary world that’s real. It exists in another dimension here cartoon characters, called Doodles, are alive. It’s Cool World. For cartoonist Jack Deebs, who’s been carried across the boundary, it’s a wild and amazing place; and he’s discovered that only some of the Doodle are friendly. Take Holli Would. She’s a knockout Doodle who’s really interested in Jack. She’s interested in using him to get herself a real body and transfer into this world.
She just needs to get her hands on one special piece of magic. The player controls Jack, who must avoid being surrounded by the Popper Police, a cartoon police force, or get arrested. Depending on how many times the player has broken the law and whether he has collected the in-game currency of nickels or not, the player will either get a lecture by Detective Frank Harris and/or be forced to pay bail money.
Ten coins is the usual bail required by Detective Harris. Players can visit Las Vegas to increase their nickel stash and store their coins at the Cool World bank. Other in-game locales include a pawn shop that allows items to be traded or bought with nickels in addition to the Slash Club where the player arranges a date with Holli Would.
At Holli’s apartment building, the player must navigate its exterior in order to reach the date with Holli. If the player did not arrange a date with Holli before reaching the top, Jack is tossed back to the ground level. In the malt shop, candy can be found in addition to other sweets. However, entry is restricted to players who have collected several pieces of candy.
