Yes, but it costs 300 diamonds per monster, or 9000 diamonds total, and I don't imagine you have that lying around unless you've purchased them (I don't think the game has even been out long enough for anyone to have gotten that many diamonds).

On the other hand, plenty of people have earned the hundreds of millions in coin required to simply feed monsters to level 15 to box them on Gold Island.
