"Jelly Boy 2" (Japanese: ジェリーボーイ2 Jerībōi 2, lit. "Jerry Boy 2") was a planned sequel of Smart Ball ("Jerry Boy" in Japan) that was supposed to be released by Sony Music Entertainment Japan in 1994 for the Super Nintendo Entertainment System (SNES).

The developer was Game Freak (which is widely known for its Pokémon franchise): Satoshi Tajiri was the supervisor, Ken Sugimori the character designer, and Yoshinori Sunahara the music composer. The game was slated for a Japan-only release. Unfortunately, the game was canceled the last minute due to a huge strain between Nintendo and Sony around the time of the game's release and Sony moving on to their own system at the time, the PlayStation.

In the proposed sequel, the player would take control of one of six different playable characters, each with a unique special ability. The game would have also featured an updated engine allowing for larger gameplay and enemy variety. Despite the cancellation, Smart Ball was not the last Game Freak game to be published by Sony. The last Game Freak game published by Sony was Click Medic for PlayStation, which was published in 1999.


The story takes place in the colorful world of Jelly Land. When five young children and a squirrel dog walk in the Star Park, an evil court jester appears and transforms them into blobs.

The game ends with Jelly Land suddenly disappearing from existence, leaving all the slime people left.
