Our tadpole has grown his back legs and has started growing his front legs. After they grow in and his tail disappears he will be a frog. Since he is an aquatic frog, he spends his whole life in the water. Nicholas wanted to get the bigger habitat for when he changed into a frog and a froggy friend. Grow a Frog (the company that we got the tadpole from) has a special that when you order the Stage 2 habitat it would come with Stage 2 Food, water crystals, sand, decorations, and a froggy friend for $14.95 plus shipping. There is a guarantee on the tadpoles and frogs that if something happens to them they will send you another one free (plus shipping.) Our Stage 2 Habitat and froggy friend arrived today. We put him in his habitat and put it next to the tadpole. Once the tadpole completely turns to a frog we can add him to the Stage 2 Habitat.
