Number six in a long series of short animated Viper-style games centering around the blue-haired protagonist, Lime. This one involves a visit to the swimming pool that goes wrong when a sunfish stuns everyone. It's actually the familiar of an angelic looking demon, and Bass has to confront it. It appears Anex86 will freeze on the disk transition, so you may wish to use another emulator.
