225. You can raise more snails by building another pen. You can either build another 5 x 5 metre pen or you can build a still bigger pen.
226. You can also raise more snails by taking better care of the snails that you have. If you take better care of your snails, year after year they will become bigger, healthier and stronger and produce more baby snails.
