Minecraft wiki entry for Fox, associated text: If any item is on the ground near a fox, it travels to the item and picks it up, and the item appears in the fox's mouth. This behavior is not limited to food and animal products; a fox can pick up any item that the player can pick up. However, they prefer to pick up food items, and if they have already picked up non-food items, they drop the non-food items to pick up food instead. A fox eventually eats any food item it picks up (besides cake) and the fox is affected by any side effects from the food, such as poison or teleportation. For example, if a fox eats an enchanted golden apple, it obtains the absorption and effects of the enchanted apple. If there is a stage 3 or 4 sweet berry bush within a 16 block radius of a fox, it sprints toward the bush and eats the berries, dropping the item it was holding. It is the only mob not damaged by the sweet berry bush, and still moves quickly. If a fox picks up a weapon or an item with enchantments, including Looting and Fire Aspect, these items affect the fox's attack as if the fox is wielding the weapon in its main hand, although the item retains its durability when used by the fox. If a fox is holding a totem of undying, it receives the effects after taking fatal damage. If a fox is holding a chorus fruit, it eats the fruit and teleports accordingly. In Bedrock Edition, if a fox wields a sword with the Fire Aspect enchantment while attacking a mob on a campfire / soul campfire, it ignites the campfire and does critical damage to the entity.
