This factory builds robots. (What
did you expect?) It's your job to
fuel 'em up once they're built.

Fillbots (ロボット工場・オイル Robotto Kōjō - Oiru?) is the 2nd game that appears in Rhythm Heaven Megamix. It's the short variation 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 variant appears later in Honeybee Tower under the title Fillbots 2.


Fillbots story gameplay

The objective of the game is to press and hold A at the right time to fuel up robots in order to make them functional, as well as releasing at the right time to prevent overfilling it. Filling them up too little or too much will cause them to not function at all. There are two kinds of robots the player will need to fill: a thin one (4 beats) and a large one (8 beats).


Button Mode

  • Press & Hold A button: Fill
  • Release: Stop

Simple Tap Mode

  • Tap & Hold: Fill
  • Release: Stop

Timing Notes

  • Hit: The robot will fly off if perfectly filled or do a little dance if just filled the correct amount for a hit.
  • Barely: If it is underfueled, the robot will appear dazed and tilt its head from side to side. If it is overfueled, it will grab its head as if it were about to explode, with its eyes growing large. A barely counts as a miss.
  • Miss: The robot will continue down the conveyor belt if the player doesn't do anything. If the player misses while attempting to fuel, the robot's head will tilt. If the player fills the robot too little, it will have crosses on its eyes and appear sad. If the player continues fueling too much, the robot will explode.

Performance Review
GradingNG 3DS
Still haven't got the basics down.
You need more practice with the big ones.
GradingOK 3DS
Eh. Passable.
GradingHI 3DS
Those robots looked content.
You filled the big ones just enough.

I fuel up the robots. They take
an eco-friendly fuel made up
mostly of fruit juice. I hear it's
pretty tasty. My lunch is dried
ramen noodles. Why do the
robots eat better than I do?

Skill Star

The Skill Star can be collected when the player fills up the first ROBO L with the correct timing.



  • This is the only version of Fillbots that doesn’t end with ROBO L.
  • In Rhythm Heaven Megamix, due to the fact that both Fillbots and Screwbot Factory appear in the game, this game was renamed in Japanese to "Robot Factory: Oil". The same applies for Screwbot Factory; its Japanese name became "Robot Factory: Screw".
  • The intro text (at the start of the minigame) appears differently between regions. In the Japanese version, the text is typed out, while the international text flashes into existence. This change is reflected on its sequel, Fillbots 2.
  • The robots make different, slightly shorter, sounds than the robots in its sequel.
