Alpacas in the island. (I'm not joking)

Hey Dick,
how are you? It's hard to live in Anchiem? Don't answer me, I don't care. I'm writing this letter to explain one thing I saw three months ago.
Ex nihilo everyone started to have alpacas as a pet. Yes, it's bizarre. I was walking with Nick and then we saw some old lady with an alpaca. At first, we didn't  give importance, but later, when we entered the park we saw a bunch of people with alpacas.
Now everyone has one, I think that is a mess have an alpaca as a pet, but hey, even Maya have one, so it can't be that bad.
Did the same happen in Anchiem? Or it just happened in Caldisla? Answer me, please, I'm quite scared.
