One Piece Wiki

Saikangaroo[2] is an non-canon animal who lives on the Island of Rare Animals and is protected by Gaimon.[1]


Saikangaroo's anime concept art.

Saikangaroo is a tall creature with a rhino-like head and skin as well as a pouch to hold its offspring like a kangaroo. It stands on two legs.[1]


Saikangaroo and its offspring were unaffected by watching Gaimon's fight with Buggy, absent-mindedly eating fruit and spitting out the seeds.[3]


East Blue Saga

Syrup Village Arc

Saikangaroo and the other rare animals surrounded the Straw Hat Pirates while Gaimon warned at them to leave the island. Later, Kamonohitsuji and other animals joined Gaimon when he saw off the crew.[1]

Buggy's Crew Adventure Chronicles

Saikangaroo and the other animals came out to look at Buggy after the pirate crashed on the island. As Gaimon declared that he had to protect the animals, all of the animals munched on more of the same fruit. While Gaimon realized the Buggy was a pirate, the animals all spat out the fruits' seeds.[3]


  • Its name is a portmanteau between the words sai (サイ for rhinocerous) and kangaroo (カンガルー for kangaroo). This also corresponds to its appearance as a rhino-like creature with a pouch to hold its offspring.
