PSP Minis Underwater Battle

In PSP Minis 水下大作战 (Underwater Battle), players control an otter in a dangerous underwater world, collecting large clams to survive shark chases. Simple gameplay with flexible controls, co-op local play possible. Cartoonish and humorous style; the otter uses agility to dodge threats while gathering resources. No deep story or named characters beyond the otter protagonist. What stands out is the light-hearted survival mechanics, catchy music, and cute underwater setting that makes it a charming bite-sized mini-game.
