The Geiger Counter is a rocket part of the Dolphin that can be found in The Forest of Hope, inside a Burrowing Snagret that ingested it. Although the part is vital to the ship's repair, Captain Olimar is ignorant to what its purpose is. He notes it "goes wild and lets out a lot of noise", but he ignores it regardless. Olimar admits he should read the operator's manual for it.
Collecting the PartEdit
From the landing site, go to the right. Break a gate with Bomb-rocks that's near the place where the Yellow Onion originally was. Defeat a few Red Bulborbs and Dwarf Red Bulborbs and then use Blue Pikmin to push a box near the water. Then you'll find three Burrowing Snagrets. The one closer to the edge has the ship part.
