Crunchy Crystal

Crunchy Crystal is a crafting ingredient obtained by butchering a Moon Fish at a Chef's Counter. It is not found as a loose world pickup; its source is tied directly to food preparation, making Moon Fish the required input for producing it.

Because its acquisition depends on access to a Chef's Counter, Crunchy Crystal is part of the game's processing chain rather than a standalone scavenged resource. If you need it, the key step is securing a Moon Fish first and then using the Chef's Counter to turn it into the material.
