Fillbots/Development

• In Rhythm Heaven, this game technically has three "versions" in the game; one for its own appearance, one for Fillbots 2, and one for Remix 1. However, all three of them are identical.
• This game was known as "Robot Factory" in preview versions of the game.
• There is a Practice theme intended for this game in Rhythm Heaven Megamix, but it goes unused.
• The tiny robots from Fillbots 2 still exist in Rhythm Heaven Megamix, but are never used. There are even short and Honeybee Remix versions of them.
• There is an unused image showing a factory with a strawberry and the number 2 in Rhythm Heaven Megamix. This, alongside the information from Fillbots's Rhythm Item, implies the red oil is actually strawberry juice.
