Thanks for all the input. I didn't realize Corns were so much more active. Makes me wonder if my daughter would have preferred a Corn. lol She often gets frustrated by the 'hiding' of our ball. But she is more active when we have her out, but not Tooo active. Sounds like with corns, you have to be on the move all the time, when they are out.
I'll be sure to pass on this info. to our friend. Thanks again!
