PHILADELPHIA (CBS) – It’s Black Friday. So what toys are selling the fastest this holiday season?

“What my son actually wanted was this MobiGo Toy Story learning thing.”

Retailers are having a hard time keeping some toys on the shelves, or online:

“I was lucky. It was the last one. So I was definitely lucky for that.”

While there don’t seem to be any “Cabbage Patch” or “Tickle Me Elmo”-style crazes this year, some toys are truly hard to find, says Ed Crotty.

He runs the toy-tracking web site zooLert.com, “The true, clear winner has yet to be decided. But the Dance Star Mickey is extremely hot; extremely hot.”

How hot is this dancing Mickey Mouse doll?

“It really only lasts for minutes in stock.”

Crotty says other contenders include Sing-A-Ma-Jigs, Microsoft’s Kinect, and Monster High Dolls.
