LOL, yes, I like it when Bloo's voice is really high pitched too. Granted, it can give you a headache after a while, but it is soooooo funny! I especially like his high squealing and jabbering in "Say it isn't Sew"- "There it is! The faaaiiirrr!!" It just reminds me of how excited I use to get when I was a kid. For instance, when I was little, I loved birds (still do, love all nature actually), and on a particular road trip to the beach when I was 11 or 12, we passed a pond where there was a beautiful Rosette Spoonbill, which look very much like flamingos, all pink, red and white, around the same size, but with a spoon-shaped bill. I had never seen one before, and it was so "rare", I got soooo excited over seeing it I started jumping up and down in the car and talking much the same way Bloo was... And my parents got VERY mad at my over excitement and grounded me for losing control. Then I cried.
Haha, but now, I'm sure laughing over it.
I have to say I like Bloo's newer voice over his older one. His older one sounded a little creepy to me at first. Not sure why, maybe just because it sounded "girly" for a boy IF. Although it grew on me, I still prefer Bloo's newer voice.
