The tools talked and sang.
As for the Little Einsteins

I'm sorry it just makes me laugh thinking about them. They actually got people that really looked like them! The best was June. Annie was just weird and Leo, well, you'll see.

It just caught us off guard. They weren't singing or talking live because they had the exact voices of the charaters on the show.
I'm glad my info has helped the 2 of you! Have a great time at the show. FYI, you can take pictures during certain parts of the show, but they say no flash photography.
Oh, as for the things for sale. They had cotton candy bags with Handy Manny construction hard hats in plastic that came with it. They sold the tool box with tools, Handy Manny doll, t shirts for all the different shows, souvenier book, slushies in special cups with the show logo, Mickey binoculars, and so many other cool things. They also had an area where your kid can take a picture with a background that for some reason I can't remember, sorry!
