Puffy (porcupinefish)

Puffy, known as Senbon (センボン) in Japan, is a virus in the MegaMan Battle Network series that resemble a blowfish. They only appear in MegaMan Battle Network 6.

Puffies remain stationary and attack by shooting needles in an arc onto the panel MegaMan is currently standing on. If Puffy is hit, but not deleted, it will inflate and shoot out two needles; if it is hit a second time, it'll inflate again and fire three needles in quick succession (once a needle has landed, the panel can be stepped onto safely). Because of this, these viruses should be deleted in as few hits as possible. As Aqua-type viruses, Puffies are weak against Elec-type attacks.
