This song was written to sound as if it was sung by Donald. Because of this, it uses numerous first-person pronouns.
This is one of the rare music videos in the model era to feature stop motion animation and live action model footage in the same time. This makes it the first time doing so, this happened again on the sixth series song, Down by the Docks in 2002.
The song was based on an original lyric idea by David Mitton.
Dilly's quacking sound is different in the Japanese version.
A version without lyrics can be seen on the official Thomas and Friends YouTube channel. It was uploaded on 2 April 2015.
As with the episode of the same name, the name of the song is a pun on that of famous Disney character Donald Duck.
According to a Youtube Comment by Junior Campbell, David Mitton came up with most of the lyrics with the exception of the "she makes me so happy" break.
Mike O'Donnell's last name is misspelled "O'Donnel" on the UK title card.
During the head-on shots of Donald with Dilly, the background and the flatbed in front of Donald keep moving due to the stop-motion animation.
Douglas is mistakenly shown instead of Donald several times.
