How?!

Barak has four kippot. FOUR. He has an excavator kippah, a firetruck kippah, a tractor kippah, and an aleph-beis kippah. Kippot one through three were custom made for him by my friend, with his name and favorite heavy machinery. Kippah number four was bought from the man with the truck. As of this moment, ALL FOUR of them are MIA. I am pretty sure they are all in the house somewhere, because I would have noticed if Barak had left the house with a kippa and returned without. Wintertime is hazardous for kippot, I know, because they get stuck in hoods and the like, but I really do think they're in the house. ALL FOUR of them. But where?!
