So I was fighting a wyvern (like you do) and I finished him off and yada yada yada when I dropped into my makeshift pond I'm making but guess where I landed, right on a mimic! *perfect*. Later I was on a fishing quest in the underground hallow and I found a mimic on the ice from the ice biome next door. I killed but later I was under the ice and there was ANOTHER mimic! All the mimics today!
