In Pikmin X: Deep Freeze
Among the smallest of shot-fish, Zipline Groinks are essentially rail-bound Ranged Groinks; instead of a windshield, they have hooked feet that let them zoom along the wires stretched throughout the Sub-Surface Construct on a predefined path. As they pass near Pikmin, they slow down, charge up a powerful explosive shot, and fire it at their target's position. Generally, they hang too high to be attacked, but Winged Pikmin are able to fly up to them and pull them down, allowing other Pikmin to attack for a brief period of time.
