Annie, Quincy, June, and Leo from Little Einstein's can be found at this meet and greet. Typically, Photopass Photographers are on hand to capture the photos and add them to your photopass account. Click here to read more about Disney's Photopass service.
JoJo and Goliath can also be found here. These are characters from JoJo's Circus, a show on Playhouse Disney.
Handy Manny has been added to the character line-up as he has grown in popularity. No tools, though.
Sometimes the characters are in pairs, as in the photos above, and sometimes they are single characters. No matter what, the characters offer lots of interaction, autographs, photos, and hugs. I can hear the Playhouse Disney music in my head as I write this. It is competing with the theme song from Little Einstein's though.
