It's a classic name, or at least a classic word repurposed as a name. If flowers and months and seasons can be names, why not Papyrus? Just meet his cousins, Parchment and Canvas. That's not really their names, but it could be. It could be.

Papyrus delights in the company of the cats, petting any that let him as he compares the pictures of the posters. Same handwriting, or similar. Is it just one person behind all this advertising? Haven't they heard of a printer??

By the time Lambert comes over, he's ventured on to checking on other things, and has almost forgotten what he ordered. "Oh my god, that's the best name. A catte. A latte of catte."
