Lizard Egg

The Lizard Egg summons a lizard pet who accompanies you on your adventures. The lizard will sprout wings like those of a Flying Snake to catch up with the player if they move too far away. It can be found as a rare drop (0.1% or 1/1000 chance) from Flying Snakes and Lihzahrds in the Jungle Temple. It is one of the rarest drops in Terraria, only beaten by the Coin Gun, Slime Staff, and not officially the Nymph Banner. This pet does not do damage to other entities.

Trivia

 * Despite the fact that the egg hatches into a lizard, it is still dropped by flying snakes.

Using exploits, it is possible to get this item without defeating the Wall of Flesh
