Amphibious. The koibra can breathe air and water.   Limited Telepathy. The koibra can magically communicate simple ideas, emotions, and images telepathically with any creature within 100 ft. of it that can understand a language.   Pressure Sensitivity. When the koibra is underwater, it can sense all creatures within 60 feet of it by detecting slight current and vibrations in the liquid. The koibra can identify the size and exact number of creatures around it, but cannot detect anything specific, such as race.   Variant: Familiar. The koibra can serve another creature as a familiar, forming a magic, telepathic bond with that willing companion. While the two are bonded, the companion can sense what the koibra senses as long as they are within 1 mile of each other. While the koibra is witing 10 feet of its companion, the companion shares the koibra's Pressure Sensitivity trait. At any time and for any reason, the koibra can end its service as a familiar, ending the telepathic bond.
