Glide. The tosculi can extend its vestigial wings while falling to slow its rate of descent to 60 feet per round, landing on its feet and taking no falling damage. It can move up to 5 feet horizontally for every 1 foot it falls. The tosculi can't gain height with its wings alone. If subjected to a strong wind or lift of any kind, it can use the updraft to glide farther.
