Blisgrowth hugs sad people with its many fluffy vines to make them feel warm and loved. This Pokémon regrows its eggs full of happiness so quickly that a large proportion of Blissey eggs on the market are from this species.
It ensnares prey by extending arms made of vines. If it senses sadness with its fluffy fur, a Blisgrowth will rush over to the sad person, however far away, to share an egg of happiness that brings a smile to any face.
