I find adding a crank to anything quaint and hilarious. Even if just photoshoppedtm
A steam whistle that required a good crank and verifying subscrrription overrr dialup would end me
Edit: it must be a crank and it has to play the all around the blueberry bush progress song like the Sid’s handy jack in the box in Toy Story 1
You could probably get a dc motor and hook it up to a really small solar generator battery. Size the solar panels small enough and you’ll have to pedal somewhat to make it through the day.
