You CAN either look in route 28 or ice path -_-
Were Do You Find Sneasel In Pokemon Soul Silver Other The Mt.silver?
Ice Cave, in between Mahogany Town and Blackthorn City.
Rout 28!
Rt. 28
So sure I've seen one in ice path but I'm looking again can't find one T_T
You find it at rt28 but at night and you have a 10% chance of finding it
