After Serebii.net and several other sites literally translated the チラーミィ to mean Chiramii, yesterday Gamefreak and Nintendo trademarked 2 official romanisations for the new Pokémon to feature in Pokémon Black and Pokémon White.

Chiramii is now romanised to Chillarmy, a named derived from "Chinchilla" and "army", however Munna has stayed the same.
