The Iron Groink is a species of shot-fish that fires harmless projectiles that knock down whatever they hit.

In Pikmin: Planetary Evolution
the Iron Groink is a relative of the Gatling Groink in Pikmin: Planetary Evolution that regularly occupies high vantage points. Unlike most other groinks, the Iron Groink launches projectiles from the top of its body, as opposed to its face. Its front is still protected by an indestructible shield, however. When the Iron Groink detects a target such as a leader or Pikmin, it showers them in vast quantities of small metal shrapnel that doesn't directly harm them but can knock them down, leaving them momentarily vulnerable to attacks from other enemies. When defeated, the Iron Groink enters an emergency shutdown mode and deactivates uneventfully, allowing it to be carried by Pikmin.
