Bunny

The Rabbit can be seen on many of the Terraria logos. It is rumored that it will be added as a pet in a later update. This rumor first surfaced because of the FAQ, where a hint is given about "cuddle" creatures to work as pets. After the 1.0.3 update, a dev blog from Tiy, the game sprite developer, was posted talking about what would come in the 1.0.4 update, with the picture of a rabbit at the end. Finally, in the same week, Blue posted the following phrase on his Twitter account: "(Tosses Vile Powder onto a cute little bunny.) "Oh.... My.... Go-"*Dies*".
