yes there is
The moon shard was in a Pokemon movie, and it was apparently given out as a Promo item, along with the sun shard.
trade a blue shard with the treasure hunter
You can find these underwater near the hunters house.
I think Clamperls have the shard,but it's completely rare.After you get the shard,go to shard collector's house.
from mossdeep surf down till you reach a house
there is no such thing as a moon shard.you are probably talking about a moon 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(:
You can not get to the moon. It's just a false rumor.
we can get a moon stone on meterear falls
all the shards for trading are found in the area west of Mossdeep in dive spots
They are hidden in grass (underwater and above water) and in rocks and walls. Press A, and you should find the shard.
