In the Ancient Castle, go to where the catapult is outside. You will find a moving 
cart with some hay on it. Bounce on it to find an extra try and some bones. To stop
it, let the cart push you towards the gate (which you open by defeating the toy 
closest to it). After it stops pushing you and starts to move in the other 
direction, stay where it stopped pushing you. When the cart returns, wait until it
is almost touching you, then bark. It will be stuck until you jump on it again.
