To do this strategy you need to be around level 30.

When you unlock Diggerlings go and buy 4 from Arthur Stout then go to Willy the Builder and buy a mine.

If this doesn't work buy the mine first. After that the Diggerlings will get started and piles of dirt will appear in the ground. Just smash or sell them.

Gems and rubys may appear as well, they will sell for a good profit.

It might take a couple of days to eventually find an egg appear above the ground.

Go to Paper Pets/Petuleas and buy a Cluckles.

Once you have done that place your egg in either grass water or soil. The only thing this does is change the color of your dragon.

Then direct your Cluckles to your egg and 3...2...1 you have the Pinata that Jardinero never got!
