I am appalled, this show should NOT be airing on the PBS network. I was watching this with my 3 year old child, she took 5 minutes looking at the show before quickly turning over to me and crying because of the blue cat-hamster creature on the screen. She then began projectile vomiting all over the tv, she was sobbing, and sick to her stomach. I later looked this character up and found out its name was STU, which sounds like a disease, which made me incredibly suspicious. I believe this show has made my daughter sick because of the disease this creature carries, this show should be taken off the air for good.. DO NOT RECOMMEND FOR ANY PARENTS LOOKING FOR SHOWS FOR THEIR CHILDREN BEWARE STU!
