Nexo food items (cubees-food-*). Every Cubee loves one snack and hates one (shown on its card, derived from its collection's theme). Feeding is the vitality engine — see Your First Cubee for the exp values.
Snack names read as items — "Bread Sticks", "Devilish Cupcake", "Void Mochi", and more — and are sold via the Shop's Items category as the owner sees fit.
