"The Slowpoke of the Galar region used to eat the seeds of a certain plant that grew in their habitat, as this was their favourite food. These seeds were in fact Galarica seeds, used to this day as an essential spice for cooking. The Slowpoke in Galar built up particles of this spice in their bodies over several generations, eventually gaining the unique appearance and behaviour they are known for today."

So, Slowpoke ate spice seeds so much that not only did particles of spice accumulate in their body, they were also able to pass these spice particles down to their children?
Am I missing something? How does that work?
