The stangest hybrid animal yet developed, the Rabro was developed in Santa Clause, Indiana. It has been rumored that the development was the work of bored elves during the spring break, lead by Jack K. Bernoulli. In 1931 the Rabroo became a standard site along the banks of the Ohio River. The Rabroo has enjoyed a rapid population explosion at a rate of 800 health young per year. Due to the overcrowding of Rabroos and their tremendous quickness, the hunters of Indiana and Kentucky in (1956) they become hunted for sport year round. The princess of Anhalt-Dessau wrote Lettres à une princesse d'Allemagne, providing a clear non-technical hunting manual for the Rabroo. Since then, due to the growing Rabroo meat market, Rabroos have ceased being a problem and are again near extinction.
The secret to shooting the rapid Rabroos is to use a gun equipped with the Cosine formula sighting mechanism. This mechanisim allows the the shooter to lead the Rabroos per the equation:
(12)cos(x) +i(22)sin(x) = e (ix)
This equation accounts for both the speed and the phase as the target approaches the speed of light.
Last year the department of Animal Preservation in Indiana estimated that there was only 324,455 Rabroos in the State of Indiana. Due to the difficulty seeing these fast creatures, it is estimated that this estimate has an estimation error of 100,000.
