Cupid

Cupid is a pet exclusive to the Mobile Version of Terraria. He holds a bow that looks as if it is always loaded. Cupid gives off light once you summon him. You summon him using the Broken Heart. You find the broken heart while mining gems. He was added in the 1.1.8 Valentines Day update for Terraria Mobile Version. Cupid does not do any damage to monsters, and will shoot Heart Arrows. Heart arrows you can also buy from the merchant.
