A Bad Day for Harold the Helicopter

"It made me feel like a Really Useless Engine!"

- Percy

A Bad Day for Harold the Helicopter, retitled A Bad Day for Harold in American releases, is the fourth episode of the sixth season.

Plot
Percy is getting annoyed that Harold keeps on delivering the mail, even though it's his job, but Harold just says it's what friends are for. One morning, Percy is happily delivering the mail, but gets stuck at a broken signal and it is arranged for Harold to take the mail for him. At first they load a few bags in his net, but Harold demands that all the mail should be loaded in so he isn't slow, like Percy. So they load all the mail into the net, and Harold buzzes off.

Just as Harold sets off with the mail, the signal is fixed. Everyone tries to call Harold back, but he does not hear them. While he is up in the air, his engine starts to rattle and then the heavy mail causes him to lose control. The mail net gets stuck in a tree and Harold crashes into a haystack. Percy was shocked and puffs over to Harold and asks if he is alright. Harold tells Percy to get someone to pull him out of the haystack, which he does at once.

Back at Tidmouth Sheds, some of the engines were teasing Harold. The helicopter thanks Percy for helping him out of the haystack and Percy said that is what friends are for.
