Octopus Machine

Octopus Machine (たこマシーン) is a Rhythm Toy in Rhythm Heaven which requires 11 Medals to unlock. There are three Octo-Pops lined up in a row. The player controls the third one, who has to copy what the others do.

Gameplay
There are 7 patterns in a set order, all involving the Octo-Pops inflating and deflating themselves, and occasionally popping the cork. If the player clears all the patterns, the game speeds up and returns to the first pattern. After the 8th loop, the tempo stops increasing, staying at ~420 BPM.

Trivia

 * This Rhythm Toy, along with Rhythm Fighter, is set up like a Rhythm Game.
