Nihilego isn't here for long. They only have 1 line in this chapter and they're used as a punch line for a previously built up joke.

However I may or may not include them as part of the various background characters in the town. So if the recording is well, I may bring you back for that.

I'm looking for some sort of alien sounding voice. Be creative about it, but make sure it's not painful to listen too. Other than that I am VERY lenient on this role.
