Bari

Bari, and its smaller relative, Biri, are parasitic jellyfish enemies which first appear Inside Jabu-Jabu's Belly in Ocarina of Time. The boss of the dungeon, Barinade, is protected by a swarm of Bari.

Attacks
Biri float around and hurt Link on contact, due to their electric stingers. This means that they also hurt Link when he stabs them. Bari drop from the ceiling and attack in a similar way. When attacked, they split into three Biri (although the Bari which attach to Barinade do not split).

Methods of Defeating
Only the bombs and the boomerang can hurt the jellyfish. One hit from either will split a Bari and kill a Biri.
