Not all Rhinos are receptive to hyper-intuition. However, these abilities are appraised on a sliding scale, and usually everybody gets some, one way or another.
We have no conscious control over these Inklings; they just pop out of wherever they hide out, and just as quickly depart. It is up to the given Rhino to evaluate the impression the Inkling has left, and share it wisely with the R. Community. Or particular friends.
Often a mesage is in black and white, but for Us Rhinos, oftener in retina-spasming color.
