Custom sprites of enemy with no official name

[Fawfulthegreat64]

I am making a sheet for a cut enemy from Paper Mario: Sticker Star. The only visual of this enemy comes from a placeholder screenshot and there is no confirmed name for this enemy. However, a heavily speculated name (and one that I've personally stuck with for this enemy until it's confirmed/denied, which seems unlikely unless the prototype leaks), is "Mander," which has some leftover instances in the code but isn't 100% confirmed to be referring to this enemy in particular. But the name certainly fits with the enemy's appearance. Would I be good submitting it under that name, or do I have to submit under an ambiguous name?
