I got to do this on my latest trip to Animal Kingdom. There was not much of a wait, so why not?
I don't hate it. I don't love it. It was fine. The young ones were clearly having a good time so I'm clearly not the target demographic. It was a lot more slap-happy, cutsey and light-hearted than ITTBAB...which I guess was the point.
Eh, it's a downgrade from It's Tough to be a Bug, but it's not a Splash to Tiana-level downgrade. I would only hit it up if you've done everything in the park and it has a short wait.
