Where do u find snorkling and any tips for getting him?
Snorkling has already had its area posted. Its fourth spot above orlen, on the road. Also try the metallo escape method
What is the metallic escape method? Been looking for it but can’t seem to find anything! 
Go to the pyramid in the desert, and look around there (: you can find metallo’s first evo. Catch it, ( careful it can be a pain to find as well ) and use escape when hunting for hatchlings. Cuts down on a little time
