Have you ever had a mole out in the backyard that spends all day digging tunnels through your lawn?
Try to be too mad, it's just looking for food.
Moles do a breaststroke through the soil with their shovel-like front feet. Along the way they encounter earth worms, a mole's main food source. They use worms as both a source of water and nutrients.
To eat them, the mole grabs the end of the worm with its sharp teeth, then it uses its front feet to squeeze the soil and sand out the other end like a tube of toothpaste before eating it.
