Raef wanted an animal center for Christmas so bad he couldn't stand it. We finally covinced him that Santa really wanted Trent to make it for him for his birthday so he could have lots of presents for Christmas instead of just one(the animal center he wanted was $140). That worked and so Trent was locked in. He still needs to stain it but made it so fun. All of the little kids that come over play with it the whole time. Raef had it filled with animals within minutes and then added trains and cars. There is a roof that velcroes on also with all of the little pieces of wood being moveable to make big and little stalls for the animals. Very cool for a big boy who believes he is Diego, the animal rescuer.
