Im not familiar with what it does. I just saw a 15/15 and 15 1/1s. What does Annihilator do?

Whats even better is that the squirrel can stop it from attacking for at least 15 turns.

Im just imagining something like Cthulhu coming out about to destroy the word and a squirrel hurls itself at it…and now it has to wait another year for another go.
