User blog:Gufuawa12/Best gold island monster?

I am starting to put monsters on the gold island, and I'm just wondering what monsters are really worth putting on the island. I can accept 3 element monsters, but I'm not ready for the expensive 4 element monsters and limited time monsters. Monsters placed so far: Mammott Furcorn Tweedle Quibble Potbelly Bowgart Oaktopus Fwog Maw Coming Soon: Thumpies
