How do you get dragonache in viva pinata

you get a dragonache by getting a mine from willy builder then getting a diggerling to dig up the egg. I havn't got it yet but it will take patience. Then, when you get the egg, go to paper pets and get a cluckles. then, send the cluckles to sit on the egg by directing it to it, then you will get a dragonache! :)
