The Pokémon Company has shared a special post dedicated to adorable Ivysaur:
Did you know? There is a bud on this Pokémon’s back. To support its weight, Ivysaur’s legs and trunk grow thick and strong. If it starts spending more time lying in the sunlight, it’s a sign that the bud will bloom into a large flower soon.
