What are the coconut pirates called?

The coconut pirates are called the Kakamora.

The Kakamora are small, aggressive coconut-armored raiders who attack Moana and Maui at sea. They appear in a fleet of fast, improvised vessels and want to seize the heart of Te Fiti, the mystical object Moana is carrying to restore the goddess.

Their coconut shells serve as armor, masks, and visual identifiers, giving the group its memorable appearance. Although they seem comic because of their size and exaggerated behavior, they are a serious threat: the attack damages Moana's canoe and forces her and Maui to work together.

The Kakamora are fictional creations for the film, not interchangeable with every creature in Polynesian folklore. Menehune, one of the wrong options, are supernatural beings from Hawaiian tradition, while Tamatoa is a single giant coconut crab. Kākāpō is the name of a real flightless New Zealand parrot, not a group of pirates. The Kakamora also return in Moana 2, where their motives become more complicated.
