Hidden Grotto 100% Regeneration
There is no activation key to get it to work. All you have to do is go in the grotto, get the item/Pokemon, leave, reenter and the item or Pokemon will be there instantly. There are cases where hidden items require dowsing machine and the Grotto won't regenerate unless hidden item is found. (works for any Grotto)
