I finished the level but never found how to get the four coins beside the enemy hatgruntz???
If you failed to get those four Coinz, you must have been at least five Coinz short of a "PERFECT!" score. There is an pointing toward a that becomez an (temporarily) when you find that fifth Coin.
Also, keep in mind that there is no 'Magic Shovel' in this puzzle, so z only need to be filled in in order to pass by ... on the other hand, z need to be dug up and filled in again to acquire any prizez.
