Sea Horses?

Just had a brilliant idea! At some point you earn the ability to summon a sea horse to ride!
Got drunk and fell off the ship? Had to walk the plank and don't feel like swimming to that island in the distance? Or maybe you just don't want to be chum for the sharks! Well with the Horse whisperer ability fret no more! Just whistle and your personal sea taxi will come to the rescue! Ride high on the open seas for a short period of time on this small but faithful steed. Lol
