Bumble Buster

Bumble Buster is a mini-game that is in Twilight Town in Kingdom Hearts II. Both Roxas and Sora can play it, though only the former gets munny. It involves killing honey bees in the Tram area in Twilight Town. Completing it faster can get you more munny (only when playing as Roxas).

While playing as Sora, it's required to beat in a certain amount of time in order to complete the journal.
