Play Zou! Zou! Zou! Rescue Daisakusen (japan) Online

Zou! Zou! Zou! Rescue Daisakusen was released for the Sega Mega Drive in Japan, though I don't recall the developer offhand. It's one of those many platformers that came out for the system, aiming for a younger audience with its animal protagonist and straightforward rescue premise.

You control a small elephant who runs and jumps through side scrolling stages. Your goal is to find and rescue your caged animal friends scattered across each level. The main mechanics involve navigating platforms, avoiding enemies and environmental hazards, and using your character's unique abilities, like spraying water to interact with objects or defeat certain foes. The game progresses screen by screen, and the challenge comes from timing your movements precisely to avoid falling or getting hit. Playing it feels like a cheerful, if sometimes tricky, race against the clock to free all your friends.
