In Pikmin 3: The Progg Wars
The Giant Ghost Pikmin is a large Pikmin soul that serves as an optional miniboss in Pikmin 3: The Progg Wars. It appears only if at least one hundred Pikmin die before its room is entered. It oozes ectoplasm, which is what its attacks are based on. It fires lasers and bullets made of ectoplasm and can slam the ground to create an ectoplasm shockwave. Although any Pikmin thrown at it bounce off, it can be vanquished by throwing exactly one hundred Pikmin at it.

In Pikmin: The Dawn of Petals
Ghost Pikmin appear in Pikmin: The Dawn of Petals after three days of a Pikmin dying. After this time, Ghost Pikmin float about the site of their deaths in their previous lives, and whistling them causes them to join the side of the leader that called them over. As they are incorporeal, Ghost Pikmin can not die, although they can interact with water and be coated in it to become Water Pikmin. Water Pikmin can touch certain hazards and obstacles to disable or destroy them; fire extinguishes, electric gates malfunction and allow any Pikmin species to break them, and enemies become stunned for three seconds. After use, a Water Pikmin's coating disappears, and the Pikmin itself reverts to its ordinary form.
