Jelly Boy 2 is an action platformer developed by Game Freak, originally scheduled for a 1995 Super Famicom release in Japan. It was never officially launched, with only a prototype version leaked. The game follows the gameplay of its predecessor Jelly Boy, where players control the titular hero using his unique shapeshifting abilities to jump, attack, and solve puzzles to overcome obstacles and enemies across levels. Featuring bright, detailed pixel art and energetic music, it creates a lighthearted, fun atmosphere. Though unreleased, its prototype circulates among gaming fans, drawing attention from retro game collectors and researchers.
