The Kratt brothers secretly "borrow" Aviva's half finished night vision goggles to go in search of a mysterious nocturnal creature. But when the unstable goggles stop working, the brothers find themselves taken in by the nocturnal society of the tarsier. As they investigate, the Wild Kratts team discovers that nocturnal creatures only come out at night and learn that eyes help a creature see by collecting the light that comes from objects all around. But when the tarsier troop is in danger of losing one of their own, Chris and Martin must tap into their newfound understanding of nocturnal living and help the troubled tarsier family.
