I'm Borborygmus, the rumble who lives in your tummy. I'm also called Borby for short. It's my job to let you know when you should go to the kitchen and rustle up something healthy to eat. No junk food please as it makes me lethargic and gunges me up. Healthy food, on the other hand, energises me and keeps me happy. Don't starve me though or I'll RUMBLE like a hungry moose!
