Blue Peter Season 18, Episode 4: Episode 4

Episode 1

Expedition Japan: Who was the 'tall, fair-haired and very red-faced European' pulling the float at Kyoto's famous Gion Festival? None other than Simon, sweltering in 90°F, and that's how he was described by five "Blue Peter" viewers who just happened to be in the crowds lining the streets! But that was nothing compared with wading shoulder high into a sea of 50,000 eels, playing the part of a Samurai warrior at the Kyoto Movie Studios and coming face-to-face with the massive 30-stone Sumo wrestlers who make Big Daddy look a mere midget. And talking of giants, see how Prince has grown during the summer break and catch up with the latest news about all the other four-legged members of the team - Goldie, Jack and Jill and Maggie and Jim.

Episode 2

Prince's Progress Goldie's puppy, Prince, spent his first night under canvas when he went to camp with the First Glen Hill Guide Company last month. All excellent experience for a trainee guide dog puppy who has to learn to ' be prepared' if he's to pass his tests and qualify as a pair of eyes for the blind. There'll be progress reports on his brothers, Buster, Sandy and Henry too, who are also being puppy walked. If you have the time and the patience to train a puppy for the Association, and you live within 40 miles of Bolton, Exeter, Forfar, Leamington Spa or Wokingham, write to Derek Freeman , the Guide Dogs for the Blind Puppy Walking Manager, at the following address: Tollgate House, Ban-bury Road, Bishops Tachbrook , Leamington Spa, Warwickshire.
