The fourse can reach speeds of up to 444.4 miles per hour (or roughly 715.19 kilometres per hour).
The fourse is able to screech, but it is not known whether it has the stunning ability like Four does.
Its scientific name, Equus quattor, roughly translates to "Four horses" in Latin, though "quattor" is more commonly spelled "quattuor".
The Fourse is apparently able to read, or at least understand drawings.
The genus Equus is real.
The fourse is the fourth original BFDI character/species to have a fan-name be confirmed as their official name. The first being the algebralien species which was a fan-name until the Jacknjellify Patreon, the second being the Fish Monster which was a fan-name until Gardening Zero, and the third being Spike Ball Speaker Box which was a fan-name up until "TWO OF THEM!? - BFDI X Inanimate Insanity 2023 Event".
