Spawning

Upon entering a Grotto for the first time the item or pokemon will be randomly decided. Entering and exiting the grotto will not change its contents.

After claiming the item or battling the pokemon in the grotto, it will be empty for atleast 24 hours but no more than 72(the amount is chosen at random) before the new pokemon or item will spawn.
