Pokémon Gold and Silver/Route 36-37

After defeating the 2 trainers, talk to the girl standing next to the strange tree (the same strange tree you saw coming in from Violet City). She'll run back to the Florist Shop in Goldenrod City; go back and talk to her there, then talk to her sister, who will give you a Squirtbottle. Go back to Route 36 and squirt the strange tree; it will reveal itself as a Pokémon:. It's the only one in the game, so if you want to "catch 'em all," use a Great Ball or Ultra Ball.
