Do this:
1. If you first go to where you first learnt the smell of the button.
2. Jump of the edge of the peak and run across the grass.
3. Run along a little, there will be a snake and you must go in the oppisite direction of the snake.
4. There will be another snake, run around it.
5. Soon in the next room you see a snake, if you make it cross it will turn its back on you or fall asleep giving you a chance to howl.
6. Run back the way you came...
7. And volia! You will have the Golden Dog Statue!
