chest and shaped similar to a squashed egg. The hide is a dark caramel
bristly fur and looks like it is two sizes too big – the whole body

Its mouth is a small lip-sphincter that forms a snout on the conical
end of the body with extremely sharp teeth arranged in a circular
array. The organs it uses to both see and communicate with are located
a yard or so back from the mouth. It is a curved pyramid made up from
three oval sections of translucent black flesh, with the one in front
twice as long as the other two so it could follow the body profile. It
communicates by creating images in the ultra-violet spectrum on the
forward eye. Two fat ridges of rubbery flesh ran along its underbelly
