Bayleef

Bayleef is a quadrupedal, reptilian Pokémon that resembles a sauropod dinosaur. It has a pale yellow body, a long, well-defined neck, a pair of eyes with red irises, a short, rounded snout, and a stubby tail. Each of its feet have a single white nail. There are a series of tubular, tightly-curled leaves around its neck and a large, green leaf, bent backwards at the stem, sprouting from its forehead.

The leaves around its neck contain a small tree shoot inside, which emits a stimulant, spicy aroma. The fragrance has a combination of energizing, stimulating, and healing effects, which, as mentioned in Pokémon Sleep, makes even Pokémon that sleep near Bayleef feel invigorated. Bayleef can be rarely found in grasslands.
