Horsetail

The Horsetail is a plant that is brownish and stiffly sticks out of the ground like a post. This hardy plant can survive in soil conditions with few nutrients. Horsetails, unlike most plants, have retained the primitive method of reproducing via spores.

In Pikmin: Redemption
In Pikmin: Redemption, Horsetails are almost completely wiped out of existence. The only living specimens are found in The Oasis.
