As everyone knows, with a few exceptions as we are about to see, the official actions to accompany Hey! Ho! Giddy, Giddy Go! Go! require you to stick your hands on your head like two rabbit ears and flap them backwards and forwards whilst knocking your knees together.

If you have ever danced along, and perhaps some of you reading this have already uploaded films of yourselves doing just that, or maybe are planning to do such a thing once you have finished reading, you will know that the intense pain that accompanies this song doesn’t just come from repeating the same few words non-stop for nearly fourteen minutes.

Ellis stood at the side of the stage and started to dance. As we all now know, the dance is an extremely simple one yet she couldn’t understand why half of Doodah’s backing dancers didn’t know what to do.

‘Perhaps they are new to showbusiness,’ she thought. ‘They might be really nervous. Or maybe the unicorn outfits are too tight.’

As the song continues, the words remain the same but the tune speeds up and so the actions get faster and faster:

Hey! Ho! Giddy, Giddy Go! Go!

Hey! Ho! Giddy, Giddy Go! Go!

Hey! Ho! Giddy, Giddy Go! Go!

Hey! Ho! Giddy, Giddy Go! Go!

Hey! Ho! Giddy, Giddy Go! Go!

Hey! Ho! Giddy, Giddy Go! Go!

Hey! Ho! Giddy, Giddy Go! Go!

Hey! Ho! Giddy, Giddy Go! Go!

Hey! Ho! Giddy, Giddy Go! Go!

Hey! Ho! Giddy, Giddy Go! Go!

Hey! Ho! Giddy, Giddy Go! Go!

Hey! Ho! Giddy, Giddy Go! Go!

As the song got faster, Ellis noticed that the same dancers were struggling to keep up. One of them wobbled slightly and nearly fell on her. ‘I know that smell,’ thought Ellis. ‘Rusty oil.’

The tempo increased again and at least half the unicorns got further and further out of time.

‘That’s it,’ realised Ellis. ‘The other Troublebots are disguised as Doodah’s backing dancers.’

It is possible to argue here that perhaps Ellis should have realised earlier, but she has had a lot to contend with recently and is still new to this world-saving business. In any case, there will be another forty-seven choruses of Hey! Ho! Giddy, Giddy Go! Go! so Ellis has plenty of time to find the others and raise the alarm.
