So, I dig through kiddo's backpack. Not there.
I run to the garage, and dig through the car. Not there.
I text my wife, who left town today on a business trip: last place she saw Unicornio 🦄 was in the backpack.
By this point I'm certain that the unicorn is at pre-K, and I break the news to kiddo, who is already bawling b/c mamá and unicornio are both gone.

My older son had a single "friend" that he loved more than anything when he was little, too. When he was just a baby and it was clear that was the one toy he'd never let go of, I found one just like it on eBay(it was not mass produced) and purchased it. Same thing as you, we had it stashed in the back of the bedroom closet. I never had a great plan on how I'd pull off a switch...the bath plan was on my list, though! It would have never passed as the same one as it was without some story. I'm glad I never had to find out.
Thankfully we never needed it and when he was 10 I gave it to him and told him I'd kept a backup for most of his life. He thought it was adorable and now the two "friends" live together in harmony in his bedroom.
