Widget

Widgets (組み立てキット) are recurring objects in the Rhythm Heaven Series. Their purpose is mentioned to be unknown. A widget is composed of a rod and one or two square nuts.

Rhythm Tengoku
While Widgets do not appear in Rhythm Tengoku, rods known as Akai Mono (赤いモノ) do appear in the Rhythm Game Polyrhythm. They are industry products whose details are kept a trade secret. They are considered hazardous because they explode when colliding with walls. In the game, the rods roll along two raised paths, and the player must press the corresponding button to raise the blocks when they reach a gap.

Rhythm Heaven
Widgets make their first actual appearance in Rhythm Heaven in Built to Scale, where they are portrayed as a white rod and nuts. The player must wait for the nuts to roll into place, then launch the rod into them to form the Widget. They later appear in Built to Scale 2, this time colored red. Workers are instructed to follow the rhythm while producing the Widgets, but they get paid the same regardless.

Rhythm Heaven Fever and Rhythm Heaven Megamix
The square mass-produced objects appear again in Rhythm Heaven Fever and Rhythm Heaven Megamix in Built to Scale, where the player must bounce around a rod while waiting for two nuts to come into place, after which the player must launch the rod into them to form the complete Widget. The company sometimes makes defective products, and a worker in product testing accidentally sold the bad parts to collectors for a lot of money.

Trivia

 * Although rods and Widgets are considered to be the face of the Rhythm Games they appear in, there are actual human characters depicted in the epilogues of each game. In Rhythm Tengoku, the factory is depicted, with what may be the owner standing outside. In Rhythm Heaven, a man is depicted inspecting the completed Widgets. In Rhythm Heaven Fever and Rhythm Heaven Megamix, the worker behind the building process is depicted standing outside the Widget Factory.
 * Rods and Widgets have appeared in 15 different games total throughout the series, while Karate Joe has appeared in 23 and The Wandering Samurai in 16.
