These animals are exclusive to Tumi and come packed in a box with seeds and full instructions. You need to fill the animal with water and soak the seeds for an hour or so, then gently cover the surface of the animal with the moist seeds. Leave the animal for a few days, making sure it is kept topped up with water. Soon you will have your own hairy animal and some home grown cress for your salads! Of course, you can keep re-using your animal over and over again. These make a fun and original present for people of any age.
