A month after I met my now-wife, I went with her to Thanksgiving at her sister's house. My nephew was two at the time, and he had three magnets: a horse, a frog, and a duck. Each of which made the respective noise when you pushed a button on the magnet.

Naturally, being who I am, I took it upon myself to swap the circuit boards around among the magnets. Apparently this caused some distress a couple days later when my nephew discovered that the frog now made horse noises.

We did not give our wedding guests the opportunity to object to our union.

TL;DR: it sounds like you have an opportunity on your hands!
