To trap an animal in a certain place, you will need a shovel. So, corner an animal against the wall or keep him/her against the pond or lake. Once cornered, dig holes around him/her. Don't let the animal escape! After making holes, the animal will be trapped! It'll be funnier if you surround them with pitfall seeds! They will fall and get really mad at you for a short time. Note that the holes disapper when you quit the game.
