Odoquaero (CS)

"These teeny tiny babus measure about three inches at the shoulder, have an extremely developed sense of smell and are omnivorous. Like Luxstruo, they have a tendency of picking favorites. Other than genitalia, there are no significant differences between males and females of this species.

Basically, they're based off of smells and stick around places where those smells are present.

Also, they can glide/float on air currents by inflating their GIGANTIC lungs >8D"
