Okay, new idea: 'Oumuamua is an interstellar 'dust bunny'

Explaining the concept of a dust bunny to small children can be quite amusing. No, it's not actually alive. It's moving around because of really small currents of wind that we can't even see. It's mainly formed out of dead skin and spider webs. No, the spiders don't actually eat the dead skin. Most of the time.
