Bio Miracle Bokutte Upa
Bio Miracle Bokutte Upa (バイオミラクル ぼくってウパ) is a platformer developed and published by Konami. It initially released for the Family Computer Disk System on April 22, 1988, and was later released on a cartridge for the Family Computer on February 26, 1993.
In Bio Miracle Bokutte Upa, players control a baby named Upa who wields a rattle. When enemies are hit by the rattle, they inflate and start floating away. Upa can jump on top of the floating enemies to reach higher places, or can push it in a direction to cause it to ricochet as a weapon. A ricocheting enemy can hurt Upa if it hits him, as well as enemies who have floated for four seconds when they explode.
