First you go to the store and click on monsters. After that, you find the Mammott monster. Buy one and wait for it to finish hatching. Place your monster on a stump. *MAKE SURE YOURE ON THE PLANT ISLAND!!!!!) After that, feed your monster until it is level 3 and breed it with a T-Rox. After that, go to your cold island and place another Mammott. Delete the Mammott and buy another one. Sell that one.
