The Pokemon Company uploaded a preview for December 1st, 2019 episode of the Pokemon anime.
The next episode Ash and Gou will learn more about Ivysaur, an evolution of Bulbasaur.
Ivysaur’s appearance is very similar to that of its pre-evolved form, Bulbasaur. It still retains the turquoise skin and spots, along with its red eyes. Ivysaur’s top fangs are now larger and are visible outside of the mouth. Also, its ears are now darkened to black in the center.
Carrying the weight of the bud on its back makes Ivysaur’s legs stronger. The most notable change is that the bulb is starting to bloom, with pink petals visible, and large leaves on the bloom bottom.
Its blossom on its back grows larger in the sunlight. As the blossom grows, Ivysaur loses the ability to stand on its hind legs. The blossom produces a pleasant smell when it is ready to bloom, it means Ivysaur is ready to evolve into Venusaur
