Lepus

Lepus is a large rabbit boss exclusive to the and  version of Terraria. It can be summoned with the Suspicious Looking Egg, which is dropped by Corrupt Bunnies and Diseaster Bunnies during the Easter season. When summoned, the message "Lepus has awoken!" will display. Lepus can be spawned at any time of day.

Lepus lays two types of Easter Eggs: small ones that hatch Diseaster Bunnies, and bigger ones that hatch another weaker Lepus. These eggs can be damaged and destroyed by the player before hatching. A maximum of 5 Lepus can be spawned from the large eggs laid by the original Lepus, and after there are five, no more large eggs will be laid. Only the last remaining Lepus will drop items.

If you defeat Lepus while an unhatched large egg is still present, it will spawn around 3-6 Diseaster Bunnies instead of a new Lepus.

Tips

 * Lepus can be trapped easily, since it can't fit through small gaps, but its smaller Diseaster Bunnies can still reach you.
 * Like most seasonal content, Lepus can be fought by changing the device's date to a day in April, when Easter is set to occur. Not all devices will allow the date to be changed, however.
 * It is possible to farm coins by creating a pit with traps (preferably Lihzahrd) and jumping in with the traps disabled. The player can then grab the coins and grapple out (with no fear due to all the dropped hearts).
 * Lepus can be easily farmed by letting Lepus shoot out it's big Lepus egg.
 * Lepus can be attacked while the player takes low to no damage by making a tall staircase mostly because Lepus has such a large and odd AI causing him to slide down stairs at the end of a leap, however Diseaster Bunnies can use stairs correctly.

Trivia

 * Lepus has an unused animation: instead of standing before making an egg, it would close its eyes and fold its ears, then open its eyes and mouth, and lift its ears up.
 * The word "Lepus" means "hare" in Latin, and is used today as the name of the genus that hares and jackrabbits belong to. Rabbits, known alternately as "bunnies" and associated with Easter, are not actually members of Lepus.
 * Lepus, Turkor the Ungrateful and the Celestial Towers are the only bosses who don't drop Trophies.
 * Lepus used to drop Greater Healing Potions even before Hardmode was added until it was patched in 1.2.
 * When Lepus dies the dead parts look like the corrupt bunny.
