Christmas decoration circuit board help

Hello - first time poster and general newbie. I'm hoping someone might be able to offer some help...

I have a Santa Christmas decoration that moves, lights up and plays music when activated by sound. I have disabled the sound by snipping one of the wires to the speaker, however disabling the sound activation is proving a little more difficult. All I would like it to do is move continuously without any sound and without the need to be sound triggered to start again.

I have accessed the circuit board and the detached the wires to the piezo speaker - the decoration only moves when I touch the wires together but then will stop once the song has finished, touching them again starts the motion but again, will stop after a song. Touching them together briefly during the motion will stop the motion and then touching again restarts the motion etc. I assumed it's like an on/off signal chain.

Any suggestions? Many thanks! Photo of labelled circuit board attached
