For the two years since one-eyed Noah's demise, a groundhog puppet and a live llama were used.
That is the first and last mention of a puppet or llama in the story. No explanation offered. Why did they use a puppet and a llama? Were they just hanging out and sort of got volunteered? Do they have the same weather-predicting abilities as one-eyed Noah? Do they have to be used together (puppet prompts llama, llama uses puppet, etc.)? HUH!?!?! Tell me!
