In the Little Tigers level there is a short cut. To access this shortcut, get an item that you can shoot forward (a bubble is a good example) then when you get to the idol with teeth. Throw the item at the teeth. They shoud now open up to make a shortcut. After opening the shortcut it will close so you'll have to do it over to do it again to take the shortcut more than once.

This is a killer shortcut that I use to get a lead. To do this you need 10 wumpa fruit and a mask. In the first tunnel (after the jump) if you look up on the right side of the tunnel you’ll see an opening go in the slope. Use the mask and jump up into the hole follow the shortcut to make it into the next tunnel.
