While this text explicitly mentions the doctor in Minna no Rhythm Tengoku, his name was removed in all other languages, as Rhythm Tengoku was only released in Japan, and Sick Beats would not be localized until Rhythm Heaven Megamix, and as such, the reference would be lost. The date mentioned in 小さないきもの報告書 (Microbe Report), August 3, 2006, is the release date for Rhythm Tengoku.In Wake-Up Caller, the moon may either look like the monster or a virus.This monster has a face which is eerily similar to that of a virus. In Mahou Tsukai, whenever the Wizard makes a mistake, he summons a monster which eats the flower instead of it blooming.In the Endless Game version of Sick Beats, the yellow blob produces random objects (increasing in variety and amount as time goes on) every single time a virus is stabbed.A single black virus appears in Remix 7, being the only time the non-blue viruses appear in a Remix in Rhythm Tengoku. The Endless Game introduces pink and black variants, requiring 2 and 3 hits respectively, which gradually add to the challenge. In Rhythm Tengoku, the normal Rhythm Game only features blue ones, which take one stab. The color of the virus determines how many hits it takes to kill completely.
