The Tchoungs are a species of small hummingbird-like creatures known for their extraordinary sense of direction and the ability to record coordinates of anywhere they've been like a living GPS, as well as to always find the shortest route to their intended destination. They are commercialized and transported in a dehydrated state, and can be brought to life instantly in contact with water (similar to the Instant Martians).
