First, make a bed out of a big slab of stone also make a large enclosure. Next, make a hutch which can contain a water trough, Fish pile (has to have 20-50 small, 30- 60 medium and 60- 120 large) and the big slab of stone. Then move it into the enclosure and provide a large pond about  5 meters wide, 10 meters long and 20 meters deep.  Also, put fish in the pond so it can catch some fresh fish but add water before otherwise the fish will die. After that, introduce it to the enclosure and have a play with it. Later on, open the hutch door and keep it open and whilst it explores it, put in toys in the enclosure. Finally, make sure it can make a ring of fire so that it can heat up the slab otherwise it will get to cold and could die as they are reptiles and need to be warm to survive.
