PukPuk Eggs are common health-restoring items that appear throughout Star Fox Adventures. Each egg restores an entire heart of either Krystal or Fox's life, which is double of that of a Dumbledang Pod.
PukPuk Eggs are also for sale in the blue room of the ThornTail Store. Fox can purchase one PukPuk Egg for six Scarabs or a few, which collectively restore Fox's health entirely. The ShopKeeper sometimes allows a bargain price of four Scarabs for one PukPuk Egg, or ten Scarabs for a few.
According to the description after obtaining the first PukPuk Egg, these items originate from PukPuk Birds, who are bred by SharpClaws for their eggs as snack treats.
