Crystal

Crystals are obstacles that can appear in many different forms. Although there exist several objects made of crystal-like materials, the standard crystal obstacle is a see-through rock. Crystals can contain objects, like fragments, pellets, and also fruits, but their main purpose is to serve as blockades. Despite there being different types of crystal-related objects, all of them require Rock Pikmin, a similar Pikmin type, or bomb-rocks to be broken; other Pikmin types will just tap away, only to give up after a bit. Some enemy attacks are capable of damaging and destroying crystals.

Large crystal
Large crystals are relatively big and are the most common type of crystal. They will eventually break if they are damaged by Rock Pikmin or a similar type of Pikmin. They can contain fruits, fragments, data files, and even spray nectar. Onions can also be found within large crystals.

Small crystal
Small crystals only need a few hits from a Rock Pikmin to break. These crystals generally do not contain major objects, and usually just pellets. They can block geysers.

Crystal nodule
Crystal nodules aren't like other crystals: they don't block paths, contains objects, or block geysers; but are the main weapon of Skutterchucks. Crystal nodules are very small white crystals, and only need one single hit from a Rock Pikmin to break. These objects can be thrown and dropped by Skutterchucks. Skutterchucks can harvest crystal nodules from crystal nests.

Crystal stalactite
Crystal stalactites are crystals that pose a great danger to anything lurking below them. When a leader, their Pikmin, or an enemy approaches a crystal stalactite, it will break from the ceiling and instantly kill them if it lands on them. To avoid this, the stalactite must be dodged by intentionally causing it to fall and then moving out of the way. This specific obstacle differs from a boulder in that it remains after it falls to the ground, partially buried.
