Fillbots 2

Fillbots 2 (かえってきた ロボット工場・オイル), known in Rhythm Heaven as Fillbots (ロボット工場), not to be confused with the arrange variant in Rhythm Heaven, is the 3rd Rhythm Game in Rhythm Heaven and the 34th minigame in Rhythm Heaven Megamix. This game is about the Fillbot Factory where robots are made, and the player is in charge of fueling them up with oil, but not too much or too little. It's also the normal variant of Fillbots in Rhythm Heaven Megamix.

Gameplay
The objective of the game is to hold down 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 it's fueled exactly on time or do a little dance if it's not exact but still good enough for a hit.
 * Barely: If the robot is underfueled, it 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.

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

Demo
A demo was released on the Nintendo Channel around 2008 for Rhythm Heaven. Unlike the previous two games in the demo, Fillbots is only playable until the end of practice mode.

Trivia

 * In Rhythm Heaven, this game technically has three graphics sets 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 is the first game in the series that show robots
 * Fillbots receives a successor in Rhythm Heaven Fever with Screwbot Factory; both minigames involve the player trying to power robots by holding down the stylus or buttons for a specific amount of beats. In the Japanese and Korean versions, both minigames share the same name. When they appeared in Rhythm Heaven Megamix, they received an additional word describing that game in order to differentiate them. This one got オイル (Oiru) while Screwbot Factory got ネジ (Neji).
 * In the minigame Cheer Readers, a full Fillbot can be seen in the tutorial, appearing on the open books during the "Ok, it's on!" cheer.
 * There is also an unused sprite of an unfilled Fillbot in Megamix.
 * The description for this game in Rhythm Heaven Megamix is taken from its sequel in Rhythm Heaven.
 * This game has a practice theme in the Rhythm Heaven Megamix version, but it goes unused.
 * This is one of the few games to keep their original controls from Heaven to Megamix, if the player is using Simple Tap Mode.
 * The others are Munchy Monk, Freeze Frame, Shoot-'em-up 2, and Lockstep.
 * This game appears in the "Wario…Where?" Challenge Train. In it, the medium sized Fillbots are made to look like Mike, and Dr. Crygor and Penny Crygor can be seen in the background.
 * There is an unused image showing a factory with a strawberry and the number 2.
 * In addition, this might also indicate the red oil is actually strawberry juice.
