How do you find shuckle in Pokemon Emerald?

to find/get shuckle in Pokemon emerald, first beat the elite four in ever grande. next go to (the) safari zone. remember the area those guys were gaurding? well you can now go in. look near the top of the area for some rocks that can be broken. there is a 10% chance that there will be a shuckle that will be there to attack you when you break the/a rock.*

i hope it helps :)

* this does not work for ruby, Sapphire, leafgreen, or redfire.
