Moon Lord Legs

The Moon Lord Legs is a vanity item that appears as random chest loot in worlds with the seed 05162020.

It features a unique walking animation as "tentacles" replace player legs.

It only takes one to research for duplication in Journey mode.

Trivia

 * The addition of this item is almost certainly due to a community petition to make Moon Lord's lower body a boss.
 * The seed used to find the legs is the date 1.4.0.1 was released, and, also, the 9th anniversary of Terraria.
