Much like real life, Coconuts in Disney Dreamlight Valley are a tropical fruit used to make scrumptious desserts or as a substitute for other ingredients. Dishes made with Coconuts will eventually be required for completing specific Dreamlight Duties, Star Path Duties, and customer orders within Chez Remy. However, players will encounter an issue: Dreamlight Valley's Coconuts are not available in any of the unlockable biomes or their corresponding Goofy Stalls.
