This platform game features the small blue-haired cutesy creatures that were popular around the time (although surely not with most computer game buyers?). Initially, you have no weapons, and contact with the nasties costs you energy, but a Yo-Yo can be collected, which can be used not only to kill enemies, but also to smash blocks away and open up paths, and even (with practice) tied to a ledge to allow you to swing across a gap. Throughout the levels, you will find the letters B,O,N,U,S, and G released from bonus balloons or on killing an enemy - if at the end of a level your letters spell out Bonus or Bogus you go to the appropriate extra level. The former has a chance to gain extra lives, the latter must be escaped quickly to avoid losing a life.
