Trivia

 * They're supposed to represent the mathematical constant pi (π), but specifically the constant but multiplied by three (resulting in 9.4247). Similar to Pi, they do have a pie flavor theme to their design, being peach custard.
 * Their relation to Nat and their entire cat theme is a reference to how this multiple's digit starts with a nine.
 * Unlike Tau, though, there has not been an "official" name for 3π, so everyone obviously decided to go with whatever Greek letter fit best. Al jokingly thought 3π is Iota, since from looking at Pi and Tau, to them there seems to be the beginning of a pattern where a line was being taken off the Greek letter pi for each multiple. This is what then lead to this character's name.
 * Jokingly they also thought "4π just does not exist lmfao"
 * They initially thought to name them Rho, as that was believed to be the name of 3π by a handful of people, and by handful of people it was a small part of the Numberblocks community for some reason. From this, Al thought to make Rho-row homophone jokes with it, but they decided LuR had "too much Numberblocks influences" and thus this idea was dropped.
 * Epsilon was another planned name of theirs, in reference to a Youtube comment Al once found saying 3π should be Epsilon, as it looks like a turned three, and references the starting digit of the constant and the number it's being multiplied by. Al decided against it as the Epsilon letter bears similarity to the Pitman digit el that Ell has, and wanted to avoid confusion.
