What's with the Krill?

When I was in ninth grade, me and my friend did a report on the antarctic tundra. We were talkin about krill (which live in the antarctic tundra) and we thought "If most words come from smaller words that mean something, then what does krill mean?" We decided that krill is a scientific word for random thoughts. Whales eat random thoughts. Whales eat lots of random thoughts. In fact, whales eat tons and tons of random toughts everyday. Why did you think we had so many random thoughts? Examples of krill: little green bugs, pink bunny slippers, a boy who wants to be a ninja, scented sticky notes, 'I would have pepper sprayed him.'
