Bruno is a baby Ottifant. It's an ordinary evening, and Bruno's dad is working late at office. Reason enough for Bruno's vivid imagination to run riot, thinking that his dad has been kidnapped by aliens! Jelly babies, that fell from his father's pocket on the way to work, blaze a trail to the office. Now it's up to The Ottifants to fight their way through hordes of terrorizing toys, Ottifant-eating plants, tear through gloomy caverns of doom and cut across a perilous jungle - workaday objects and boringly normal settings as seen through kids' eyes - and rescue his dad!
Picking up jelly babies, blasting enemies and collecting papers gives points and raises Bruno's score up to a fixed value of 9,999 pts. There are several entrances to secret rooms hidden in the five worlds. But, unlike the Genesis-version, the rooms are quite small and basic and there is no 1,000 point reward by completing them. On the whole there are two different tunes backing your journey through the game: one for the stages and one for the boss enemies. The varied background music and sound effects of the Genesis-game are completely missing, as is one entire world: The Garden.
