The case of the missing hot pink Croc

We have turned our house upside down and cannot find the match to Alli Claire's hot pink Crocs. She wore them to school Monday and I haven't seen it since we got home. Martin even went thru the trash thinking she might have thrown it away. We've looked EVERYWHERE except that one place she's crammed it in. Any ideas anyone?? I'm to the point of just going any buying another pair. Who would have thought this would be so difficult to find. I'm mean, it's hot pink after all, right??
