Blisninja is typically used in Pokémon Centers and can quickly run to sad Pokémon to give them an egg, hoping to help them feel happy. Blisninja puts its egg in its mouth when threatened.
It appears and vanishes with a ninja’s grace. If it senses sadness with its fluffy fur, a Blisninja will rush over to the sad person, however far away, to share an egg of happiness that brings a smile to any face.
