This level is very hard. Again it is most important to reach the treasure room quickly. There are not enough Diggy Blocks, and there are not enough moves either.
1st board: Clear the blocks normally. Forget about the given color bursts, you can use them only after too many moves. Use the Dynamite to clear the entry or exit. 88,000 points in Diggy Blocks.
2nd board: Clear the blocks normally. Exit to the right, but get a lot of the Diggy Blocks first. It is the only board which is fun to play. 78,000 points in Diggy Blocks.
3rd board: Clear the blocks normally. Mud ninjas at entry and exit, and everywhere else, make this board a hell. Use the Dynamite to clear the entry or exit. But this board will need so many moves that you never have enough in the next to make the required points. 66,000 points in Diggy Blocks.
