| “ | Think these contrasting compatriots are on opposite ends of the gene pool? Think again! The Bisonorus is, in fact, two bonded Monsters of the same species but different castes. At birth, the pampered Emperor Bisonorus perches atop the rounded dome of an eager-to-please Standard Bisonorus, where it will spend the rest of its days. Despite this inherited hierarchy, the Emperor Bisonorus prefers giving head scratches to giving orders. | ” |

| “ | Strengthening the ties of their kinship with age, the Emperor and Standard Bisonorus now prefer to make decisions by committee - even if it’s a committee of two! All choices are subject to a vote, from their lunch menu to their weekend plans. In the event of a deadlock, the Bisonorus simply plays a high-stakes game of Earth-Paper-Scissors. Interestingly, the Emperor's luck never seems to run out... | ” |

| “ | This Bisonorus returned from the Prism Gate forever changed! In addition to some adaptions for paddling through murky subterranean pools, the molecular alteration also body-swapped the consciousness of the Standard and Emperor Bisonorus, undoubtedly leading to hijinks the likes of which have never been seen before - extraordinary! | ” |

The Standard Bisonorus has a deep/whispery voice, it sings "Dum, dum, dum, diddly dum!", while the Emperor Bisonorus echoes the sound. On Cave Island, it sings in a more elder-like and english accented voice.
Mimic makes a similar noise on the Continent while copying it.

Notes[]
- Bisonorus' name comes from Bi, meaning 2, Sonus, the Latin word for sound, and Cernos, Greek for horn - it is also likely a reference to the bison. The word sonorous also refers to a deep ringing sound, which fits with Bisonorus' nature of vocalizing in a deep, reverberating voice.
- Bisonorus was announced in My Singing Monsters Live #35 on July 5th, 2019, together with a naming competition for its default names.
- The following weeks episode of My Singing Monsters Live announced the winners of the naming contest. It also revealed an image of Bisonorus' egg.
- Incisaur, the previous Fire Monster released, was also revealed in the same fashion.
- Bisonorus was originally a Monster known as "Doose," and it was supposed to be released alongside Congle with a entirely different design. However, it was decided at the last minute that the design needed some tweaks, and it was sent back to the drawing board. It was, in fact, so far into development at the time that it was teased on the Version 1.15.1 login screen for the game; you can see a few orange feathers sticking out from above a mountain. Players incorrectly guessed that these feathers were actually the eyes of Congle.[1]
- The Standard Bisonorus is a lot more chatty than the Emperor, typically asking questions and making suggestions. The Emperor doesn't typically talk as much, but when it does, it is very straight to the point and typically replies with a "yes" or a "no." This explains why the Emperor Bisonorus doesn't sing that much.[1]
- There is currently a bug where the top of the Standard Prismatic Bisonoruses' mouths are grey.
- There is also another bug where the Standard Blue Prismatic Bisonorus' eyelids turn upside-down during its singing and sleeping animation.
- Originally, the portraits for Young and Adult Bisonorus used early versions of their designs. The former was also originally Bisonorus' shop icon until the release of Version 2.0.
- All monsters that make up Bisonorus in breeding is a vocalist except for Rootitoot and Quibble.
- Bisonorus' part is imitated by Mimic on the Continent.
