Editing Iron ball

The '''Iron Balls''' are objects found throughout ''[[Pikmin 3]]'' that serve as an intractable [[obstacle]], much like the [[cardboard box]]es. They are very plain metallic-gray orbs with "20 weight" inscribed on them. As the number would imply, 20 Pikmin are needed to push them.

Iron Balls are always placed at the tip of a slope, so they will rush down a fixed path once the Pikmin have set one in motion. With its momentum and weight, it will break open walls the Pikmin could not have torn down themselves. This opens entrances and exits to other parts of an [[Areas|area]]. Creatures in the ball's path will be killed, allowing the player to defeat enemies in some rare cases, but Pikmin are more likely to be crushed if the player does not pay attention. [[Rock Pikmin]] will survive the hit.

*[[Distant Tundra]]

**One is atop the slope where the Yellow Onion is. When it rolls down, it destroys the blockade on the cave's main exit.

**Another ball serves as the "nose" on [[the President]] snowman figure. When pushed out, it rolls until it destroys the blocked entrance to the cave with the [[Vehemoth Phosbat]].

*[[Formidable Oak]]

**The room with the [[bridge]] and [[Arachnode]] has the final ball in Story mode. When pushed, it rolls down a slope and destroys a [[crystal wall]] down below.
