Come Back Gizmo

Today i read come back gizmo
this book is really good. I think it was really mean how the boy locked biscuit in the car boot.An adult found the dog biscuit and gave him a gizmo.
I think it is funny because the gizmo turned the boy in to a dog and the dog in to a boy.When the dog who was the boy tried to speak but all that came out was a woof.The boy who was the dog didn't know any words because he was a dog.
