Hiso Hiso no Mi

The Hiso Hiso no Mi, also called the Hiso Hiso Fruit, is a Paramecia type Devil Fruit that allows the user to understand the heart of an animal or in other words allow him or her to speak to animals. "Hisohiso" means "whisperingly." It was eaten by Apis. The power of the fruit was first demonstrated but not clearly explained during the moment when the Marines under Nelson discovered that Apis was aboard the Going Merry and began attacking the ship. Apis learned from the seagulls that a strong wind was coming their way thus allowing the her and the crew to escape from the pursuing Marines.

Strengths and Weaknesses
While the fruit's powers enable the user to communicate with animals, it should be noted that its influence does not extend to controlling the will of the animal.
