It is a great show for toddlers -- frankly there should be more kid-friendly type of shows like this in the World.
It's a puppet/stage show where you basically get a typical "episode" of a Mickey Mouse Clubhouse show (There's a problem .. they have to solve it).. except it combines several of the other shows into the storyline (Jake, Sofia, Doc) ..
The audience is really close to the show. A unique attraction in my mind and though not quite as interactive and intimate as Enchanted Tales with Belle .. I think it ranks up there for a fun show for the pre-K kids.
Tried it for the first time in August and enjoyed how much my son and the kids sang and danced along to the show.
1) Dont' waste a FP on it .. plenty of seating and plenty of shows throughout the day. I used one and the theater was half full. Even though there really isn't many Tier 2 choices at DHS that you "need" Fast Passes for, we could have used it for something else.
2) Take the kids twice .. my group of toddlers wanted to see it again

.
3) Go early (like the first show) so you can spend some time before (or after) visiting the Disney Junior Meet and Greets outside the show.
(NOTE: The M&G characters are full life size ..while the characters in the show are puppet-sized. My son had issues with all the Disney Junior M&G characters. They were just too big and scary for him . (especially with those gigantic heads).
