>>33174881Plenty of evidence both in Ashnime and games lore like the book in DPPt that talks about pikcing the bones of pokemon
Pick clean the bones of Pokémon
caught in the sea or stream.
Thank them for the meals they
provide, and pick their bones clean.
When the bones are as clean as can
be, set them free in the water from
which they came.
The Pokémon will return, fully
fleshed, and it begins anew.
