Sleeper Trees are small fruit-bearing trees found in End Wood of the Forests of Silence, that grow wherever there is a source of shallow, still water. They have slender trunks, and grow fruit shaped like fat pears with golden skin flushed with pink. When the fruit of a Sleeper Tree is eaten, the victim falls into a deep sleep, and the only way to wake them is to feed them the bitter tasting skin. However, both Filli and Kree were able to eat the fruit without falling asleep.
