Mollusk are a family of viruses in Mega Man Battle Network. Mollusk are protected by a bubble, which must be broken prior to dealing damge (it can be broken by a strong attack or a couple of uncharged buster shots). After a couple of seconds, this bubble regenerates. Their movement consists of teleporting to a panel in the same row as the player. They attack by releasing a non-homing water tower that goes forward in a straight line. Stronger variants have stronger bubbles, requiring more damaging hits to break them (or more shots from the uncharged buster).
