Could someone please identify this cutesy one?

Thanks!

Hi there. I'm an amateur cactus collector. Last weekm I grafted a few cacti pups on opuntia pads. Here are the results. I grafted 6 specimens, but only 3 succeeded. I can't wait to see them grow! The scions are growing as I can see new growth of spines. http://www.cactiguide.com/forum/userpix/1470_o...
