Trivia

 * Having candy used showing on a pet usually makes players consider it lower value, especially if it's not max level and its candy uses have been wasted with lower quality candies.
 * If a pet with or higher rarity has gained enough XP to be max level even without the XP from the candies, the number of candies used will disappear. However, it is still exposed in the item's NBT data, and may be shown by mods or third-party websites such as SkyCrypt.
 * Feeding a pet non-candy food, or candies with the, will not have a visible effect on the pet, even in its NBT data, and is therefore practically indistinguishable from leveling it naturally.
