Chametz Imp

(n.) A mischievious little creature that likes to throw out people's bread and grains and burn it, and they get especially rampant during Passover. Occasionally, they'll even hide your matzah if you aren't paying attention. If you ever spot a chametz imp, don't chase them. Just let them do their thing. Eventually they'll get bored and leave. But they never leave for too long, they always come back in around a couple weeks. Chametz imps look like little cubes with the flag of Israel on them.

"That darn chametz imp burned my bread! I was going to eat some toast!"
"It's Passover, dude."
"Oh..."
