Bayleef is a quadrupedal, pale-yellow reptilian Pokémon that resembles a sauropod dinosaur. It has a long neck, red eyes, a short, rounded snout, and a stubby tail. Each foot has a single, light gray nail. Sprouting from its forehead is a green leaf that curves back over its head and around its neck are a series of tightly curled leaves. Inside the leaves are small tree shoots.

The aroma wafting from the leaves around its neck has a spicy scent and has various beneficial effects on those who inhale it. The fragrance has a combination of energizing, stimulating, and healing effects. Bayleef can be rarely found in grasslands. As mentioned in Pokémon Sleep, any Pokémon sleeping near Bayleef will feel invigorated.
