Jakkos are found only in the Cardon Sub-Gate, in a large room where they come out of Jakko's Nests.

The Nests sit still and are unable to move. However when approached they will unleash a large number of Jakkos from within. Jakkos hover and then dive at their opponents. They will continue to swarm in numbers until their Nest is destroyed. If the Jakkos are blown up, the Nest will continue to release more and more of them until it is either destroyed or left alone.
