Crystal gate

Crystal walls are a gate that requires Rock Pikmin or two bomb rocks to break. The gate itself consists of a slab of glass or crystal stuck between two clamps and will crack as it is damaged. Once enough damage has occurred, the glass shatters altogether. The clamps on either side of a crystal wall may be dark and rusted, light and rusted, or free of rust.

In Pikmin: Shipwrecked Stargazers
In Pikmin: Shipwrecked Stargazers, crystal gates function as they did in. The Venowraith is capable of summoning walls made out of its own crystalized venom as its fight goes on, which can be broken either with Rock Pikmin or by having the Venowraith attack it itself. They'll also crumble over time.
