While traveling to their next destination, Ash and his friends decide to take a rest in a clearing in the forest. Ash decides to release his Pokémon to play, but the newly-evolved Bayleef unintentionally Tackles him, failing to understand that her increased size is a problem. Later, they play a fetching game; Bayleef, determined to win, uses her size to her advantage, knocking the other Pokémon away and easily winning. She then runs to Ash and again tackles him, accidentally sending Ash into a nearby stream. Ash is upset and scolds Bayleef, but Brock tells him that Bayleef only just evolved and it will take some time for her to control her power. At lunchtime, Bayleef tries calmly approaching Ash, but he misinterprets her intentions and tells her to stay away. Hurt by this, Bayleef runs off without anyone knowing. While they are eating, Misty notices that Bayleef is gone and tells Ash. Meanwhile, at the side of a river, Bayleef angrily kicks a rock towards some bushes, provoking a swarm of Beedrill. As she runs, she steps on a loose rock and falls into the river.
