Thomas & Friends - Season 7 Episode 20

It is the time of year for the Summer Fete. Harold the Helicopter wishes that he could help too; but he's so busy with his patrol duties that he doesn't have time. This makes him sad. Later, however, his friend, Pegasus the Horse becomes stuck in a ditch and needs help. So Harold flies to the rescue by lifting him out of the mud and Pegasus is flown to the Fete - giving Percy quite a shock as to seeing what he thinks is a flying horse!
