Sourberry

The Sourberry is a species of spiderwort that produces berries that fall to the ground on their own, bursting upon impact and splattering their irritating juice in their vicinity. Pikmin that come in contact with a Sourberry berry's juice will panic.

Darryl Omg's version
Sourberries are plant obstacles in the form of smaller, shorter, Burgeoning Spiderwort that continually produces black berries that then fall to the ground. The berries themselves have a withering effect on Pikmin, putting them at a disadvantage upon exposure. Destroying the Sourberry will make it wilt away and stop producing berries.
