Upa crawls around armed with a magic rattle. When an enemy is struck with this rattle weapon, it inflates like a balloon and slowly floats away to the top of the screen. When inflated, enemies can then be used as temporary floating platforms to climb to higher places or used as weapons if they are pushed. He can also become temporarily invincible and gain the ability to walk if he obtains a special power-up.
