Any cat could knock over a small tank. Cats can be fat suckers with enough guts to knock stuff over. My cat as a kitten would work at things to tip them over to get a big response out of me. This cat can also open doors and comes when he's called, they're not stupid.
I'm sure no one appreciates you how are insinuating that Emily put her corn at risk.
