I only now have heard about the llama saga. The only value I could possibly add is to ensure that you’ve all read one of Odgen Nash‘s best:
The one-l lama,
He’s a priest.
The two-l llama,
He’s a beast.
And I will bet
A silk pajama
There isn’t any
Three-l lllama.*
(*Nash always added a footnote to the poem: “The author’s attention has been called to a type of conflagration known as a three-alarmer. Pooh.”)
All the best.
¿Cómo se llama?
