How can I get Stockpile on Toxapex in Sword and Shield?

Question

Toxapex could learn Stockpile as an Egg move in US/UM, but it's no longer an Egg move in Sword and Shield.

Comments

According to Serebii, it is still an egg move. Have you tried breeding it in-game?

Answer 1

Currently, Toxapex cannot be taught egg moves. If you were looking for competitive Toxapex, I would suggest looking at the best moveset questions for Toxapex. He has so many other options with having access to infestation and rest. (Sorry if this info is incorrect, I’m still not completely informed of the differences from gen 8 to gen 7.)

Answer 2

So Toxapex doesnt have Stockpile as an egg move but his pre-evolution, Mareanie does. So you can still get it through breeding as you normally would. I got one myself, bred a toxapex and pelliper.
