Today's creature is a Molukka.

It is the main prey of the cats and very abundant on their planet. They all have long whites ears which they use to attract other  Molukka's but which also attract the Cat's and other predator’s. The cat's believe that the Molukka's use their ears to 'talk' to each other as they flick them in quite complicated movements and other Molukka's seem to respond to the movement.
