Sun
It crawls onto the land in search of food. Its water bubble allows it to breathe and protects its soft head.
Moon
When it comes across enemies or potential prey, this Pokémon smashes its water-bubble-covered head into them.
Ultra Sun
When two Dewpider meet, they display their water bubbles to each other. Then the one with the smaller bubble gets out of the other’s way.
Ultra Moon
It can only breathe oxygen that has dissolved in water, so it wears a water bubble on its head when it walks around on land.
Sword
It forms a water bubble at the rear of its body and then covers its head with it. Meeting another Dewpider means comparing water-bubble sizes.
Shield
Dewpider normally lives underwater. When it comes onto land in search of food, it takes water with it in the form of a bubble on its head.
