What do we get for doing the item thing in the laboratory? I want to know because I don't want to waste my time then get a horrible prize :/

if youare talking about the 50 Rubies and Sapphires/10 Nuggets:

once you gets 50 Rubies/Sapphire and donated them to the Laboratory, it will give you leftover
Once you get the 10 Nuggets and give them to the Laboratory, it will gives you Black Sludge

Note both option only have 50% change of obtains the items.


Leftover: Restores 10% hp everyturn in battle
Black Sludge: Works like Leftovers but only on Poison Type Pokemons

here a items list and whatit does to every items in the game:

Alright Thanks :D. Looks like i'm gonna have to buy an item finder and start searching to get leftovers.

I know you could get also golden nugget some are just high in value to see some can be keepable for future use like golden nugget on halloween
