you have to get a blue shard and then give it to shard dude (i dont know his name) BLUE SHARD=WATERSTONE RED SHARD=FIRESTONE YELLOW SHARD=THUNDERSTONE GREEN SHARD=GRASSSTONE
Red Shard Blue Shard Yellow Shard Green Shard Violet City and Fuchsia City
not quite sure but i think route 212
I think Clamperls have the shard,but it's completely rare.After you get the shard,go to shard collector's house.
trade a blue shard with the treasure hunter
You need to have to get a red shard and trande it to the shard hunter.....i tihnk he is a little bit off of the coast of mossdeep
You can find these underwater near the hunters house.
from mossdeep surf down till you reach a house
find a blue shard near the hunters house in mossdeep city then you trade him the blue shard for a water stone same goes for other shards red shard= fire stone i believe blue shard- water stone green shard- leaf stone
get a blue shard and talk to the treasure hunter. his house is on the water before Mossdeep City. give the shard to him and he'll give you a water stone(:
