As all children know, toys come alive when no one is around. I mean, it's the WHOLE premise of Toy Story after all.
As I type, I can hear one. It's a motorcycle of Anson's...probably a Power Ranger one and it's ON. Every so often it goes, "BZZZ," as it tries to escape the box that it's couped up in. Only (and here's the mysterious part) I can never find it. I can sit in the boys' room and hear the BZZZ, but I can't locate it fast enough to shut it off.
Anson will be able to find it, but I'll just have to wait until he comes home.
