I find this flash disappointing. The reason why is if anybody have seen a decent amount of Sesame Street, they would know where this song came from. Hell, the song from Sesame Street isn't even the original. The idea of this flash isn't original at all to me.
I understand that this is about a two year old animation, but if I seen this when it first came out, I'm pretty sure I would feel the same.
As for quality for this flash, I will give props for. It was clean and smooth.
I just don't find the idea for this flash original at all.
