Frilleaf is a small bipedal green lizard-like monster with an ovoid head. It has two oval eyes that are bisected horizontally; the top halves are white while the bottom are black. The top half of Frilleaf's head and most of the torso are light green, while the bottom half of the head, the stomach, hands and feet are pale yellow. The creature's feet and hands each have three digits, and Frilleaf has two orange circles on its cheeks. It also has two large leaves emerging from either side of its head and a small, curled, dark green apendage sprouting from its scalp. Frilleafs also have long tails with two orange bands and an orange seed on the tip.
The leaves on the sides of Frilleaf's head are usually folded back, but can be opened up to frighten away predators. They also open up when Frilleaf attacks. The leaves can act as solar panels, soaking up sun to give Frilleaf more energy.
Frilleaf is a very friendly and curious Meta Monster. They are very innocent creatures who don't always know right from wrong.
Frilleafs are normally found in grasslands, although they can be found in scrub-like areas.
"When Frilleaf is frightened, it opens up its leaves to scare away predators. Those same leaves can be used to soak up the sun's energy."
