How do I get a rabbit’s foot?

In Stardew Valley rabbit's foot can be obtained a number of ways:

• With high enough friendship, daily luck, and mood you can get this item from a Rabbit.
• It is a rare drop from Serpents, which can be found in Skull Cavern.

A pata do coelho do Vale do Stardew é necessária para completar o pacote do Encantador. A recompensa por completar este pacote é 5 Gold Bars.

Misc

Este item é necessário para completar o enigma encontrado na Nota Secreta #20, que requer que você siga um conjunto de direções pela cidade, terminando com você falando com um caminhoneiro e dando a ele a pata do coelho. Você receberá um charme especial, que ao contrário do pé de coelho, na verdade aumenta a sorte diária!

Aparentemente o pé também ajudará a evitar um resultado negativo no Evento 10-Coração do Grupo.
