Pokemon can't dig up items, but there are Pokemon with a special ability which makes them able of finding an item after a battle there is a 10% chance. This ability is called pick-up.
These Pokemon are:
aipom, zigzagoon, linoon, munchlax, phanpy, teddyursa and meowth.
I think you need a Pokemon with a specialy natural ability that will dig up items if you walk over them.
dig
you make a dig and it will explofde and all will live happy
Get a Pokemon tha knows dig,escape rope,or just go to the exit
In the underground
In Pokemon FireRed and LeafGreen, Diglett can learn Dig at level 17, which is a nice and early level for a good move.
You earn it as a reward after battling the Team Rocket trainers in a house northeast of Cerulean City. Battle them, win, and Dig is dropped.
Any Pokemon that are ground type should be able to learn DIG. Hope this helps :)
