In Pikmin 2... Again?
A goop-berry is a item in Pikmin 2... Again?. It is a gelatinous purple berry that can be obtained from dirt mounds in much the same way as bomb rocks and can be used like them. While it doesn't inflict as much damage as an explosion, its poisonous juices have more range, leave a lasting puddle in its immediate vicinity, and gradually drain the health of most exposed enemies. Likewise, only White Pikmin are immune to the goop-berry's juices.
