In my setting there is a race of vaguely humanoid creatures that are related to the aye-aye lemur and accordingly posses many strange features such as:
•Large ears and extremely good hearing far beyond anything human.
•Good night vision and smell.
•Extremely adept climbers who can move swiftly and silently.
But they have some weaknesses.
•They are quite small, being about a meter tall.
•They are slow and awkward on the ground.
•Their fingers are too specialized to use most human tools, but they can use knives, blowguns, and open doors fine. Don’t give them a heavy weapon or bow, nor expect them to work on anything complex.
Cognitively they are about as intelligent as a human with some weird mental quirks that rent relevant to this question.
Humans have access to these creatures and wish to use them, what would be the best usage for this creature given it’s sharp senses and stealth?
