"Dragon werewolves..." What a thought. "But why stop at werewolves? Maybe, they're not-dragons, turning into dragons. Even those fish babies! A basket of weredragons."

Papyrus has absolutely no idea what the word for a group of dragons is, but whatever it is, the were-variant is probably a different word. Maybe there isn't an official one, and he's just coined it.

Still, brainstorming brilliant ideas and even more brilliant terminology aside, there's something to Angus' metallurgy thoughts. Easy to shape, healing powers... Turning into purple thorns seems like the opposite of healing. He just needs another minute to mull things over.
