Fillbots

Fillbots (ロボット工場・オイル) is the 2nd Rhythm Game that appears in Rhythm Heaven Megamix. It's the short version of Fillbots from Rhythm Heaven. In this game, the player is in charge of fueling Robots with purple liquid oil at the robot factory.

The normal version appears later in Honeybee Tower under the name Fillbots 2.

Gameplay
The game takes place at the feuling station of the factory, where robots fall down and assemble themselves on the right side, and then move down the conveyor belt to the fueling pump. The objective is to hold down the pump at the right time to fuel up robots just the right amount. Failing to follow this causes the robots to manfunction, or not function at all. There are two kinds of robots the player will need to fill: a medium one (4 beats) and a large one (8 beats).

The background contains beakers with oil bouncing through them (timed to the offbeats in the music) and gears moving the conveyor belt.

Skill Star
The Skill Star appears on the first ROBO L in the game.

Trivia

 * The "OK" noise the robots make is done one beat earlier compared to Fillbots 2.
 * Fillbots and Screwbot Factory share the same name in the Japanese and Korean versions. As both are present in Rhythm Heaven Megamix, their names were altered with an additional word to differentiate them. This game got the word オイル (Oiru) while Screwbot Factory got ネジ (Neji).
