Bayleef resembles a pale yellow sauropod dinosaur or a lizard. It has curled leaf-like growths, stated to be buds with small tree shoots inside, sprouting in a ring around its neck. A large leaf shaped like a scythe protrudes from its head. It has red eyes, and has one large toenail on each of its four feet. It also has a small tail.
The aroma wafting from the leaf-like growths around its neck has a spicy, very sharp, distinctive scent, and all nearby Pokémon who inhale it become excited and want to fight. The scent energizes those who smell it, so much that they may even become aggressive.
Bayleef are calmer than their previous stage, Chikorita. However, the scent that wafts from their leaves serves to make people excited and can cause them to want to fight.
Bayleef are very rare Pokémon mostly found in large open plains or small forests with other Chikorita, Bayleef, and Meganium.
This Pokémon was unavailable prior to Generation I.
