Rewards from digging in the mountains include:
- items for Grandpa Smurfs Tasks (Magnifying Glass, Pyjamas etc.)
- XP and Coins
- Resources (Wood, Stone and Dye)
- Gems that can be placed on the ground
Once a Smurf has finished digging it will wait until the reward has been collected. Because only magic shrubs, which do not wither, are available in the mountains and digging rewards do not disappear before they have been collected, it is not as important to come back to the mountains in time as it might be on either the mainland or the island where crops could wither.
Unlike the other mushroom houses the once in the mountains cannot be customized (yet) and there is only an upgrade for 4 Smurfberries available for one additional Smurf, which means the maximum is only 2 instead of 3 Smurfs per house. It is also possible to buy additional Smurfs without houses for 5 Smurfberries each.
