Since Bloo can not annoy me, I like his high pitched voice a LOT more. I remember I saw the Swedish House of Bloo's first and his voice was high pitched in that one... so the dubbers must've watched the first season and tried to mimic the later season episodes... so when I saw the english version of that episode I was SHOCKED XD I had seen many later episodes in english beefore watching house of bloo's in english
I love those moments when he goes REALLY highpitched, like in the halloween episode (the latest) when he goes "NOONE WILL EVER NOTICE!!", about burying Mr Herriman XD I also think he and Mac has a great sync when both are in that state (maybe it's something he inherited from Mac

)
