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.
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.
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.
- 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.
