There are only three Po s I am aware of -
PO - the red tellytubby
PO - one of the police ( or army, cant remember which!!) horses
POetry and Jazz-( NOT named after the aforementioned tellytubby, he was/IS so gormless it suites him perfectly!!) my "racehorse" who (in short!!) I bred, broughtup, gave to Philip to train, had no steering (not P's fault, I hasten to add!), came home, got reschooled so he had steering (after a fashion!!!) returned, ran another 4 times, best placing was 6th of 8 (i think!!) with a flattering RP comment in running ( the best thing they said about him on the day ever was "dont bother with this one - watch for the entertainment...." !!!!) went to the Scottish Racing Academy - hated it, turned into an unrideable, unhandleable lunatic,camae home, was fine, came with me when i started new job - went as a companion, had to move as people gave up horses, got rehomed to Runcorn, VV happy, spoilt rotten and loving life.No longer a mummys boy.
Then theres PAU - in Spain i think, where the World Equestrian Games were held a few years ago
Any of them help???!!!
