>>41805623I just got it to work and hatched mine, the anon explained it wrong though, you were supposed to use the xp item on the pokemon in the first slot and press and hold down at nearly the same time you press A, it will be used on the in the second slot instead, have a level 100 in the first slot so you don't accidentally use the item on the first slot pokemon, your pokemon screen should look like
>Level 100>Dreepy>Egg
