Ultra Balloon

Inside the Robinson Household, the Realm of the Toy World within the Baby's Room has been corrupted along with their king. Ultra Balloon is a Bubble Bobble-like game where the player controls one or two babies turned into penguins. The goal in each stage (called "Story") is to go through a series of levels, trapping enemies in bubbles and bursting them with the option to collect items for bonus points, until you get to a final level to take out a boss and rescue a girl. The music is based on various classical tunes including Phantom of the Opera and The Blue Danube.
