the nearby towns of Rivers Bend's distress. He also discovers the location of the salamander inadvertently, and is able to pass the information to the Doctor. The latest salamander has been attached to the Jambaroo Shield, a trophy which is to be presented to the winner of a horse race called the Jambaroo Shield stakes. The children decide to enter the race with Victory Stride as their champion, but he needs a trainer. Dingle has been sent to buy all the other horses off; Sator wants to win the race for himself. He purchases a horse called Black Eye, and a jockey. Dingle then keeps an eye on the children and sees them searching for the mineral along the river. It transpires that old Sid Chesney, a horse-trainer the children have been able to persuade to train their horse, also knows of the whereabouts of the fifth mineral, for he was the person who found the Salamander originally. After they have the mineral safely in their possession, they are about to go to the race when they find that their bus has been sabotaged by Murk who has sawn the drive shaft through. Race day arrives and Sator is filled with rage to see the Poopmobile flying to the race course, with Victory Stride slung underneath it. Sid Chesney has trained the horse well, and although Alice cannot ride it herself, because of an accident, Jamie has been prepared for the ordeal. The race begins, and Dingle tries to send Jamie in a different direction by planting a confusing sign on the course. Sators jockey throws dirt in Jamie's face, and tries to push him from the horse. But Jamie hangs on, and even though Sator has planted a fresh horse on the track, Jamie still wins the race, with a little last moment help from Sid. The Salamander is theirs, but they are horrified to find that there is no cryptogram on it. And to make matters worse, Dingle has planted a vision bug on the Poopmobile which even Matt is unaware of. Part 6: The last mineral In the Poopmobile as they return from their last adventure, Peter uses an old trick to divulge the secret of the last Salamanders cryptogram. At the base camp, they decipher the coded message and to their amazement they discover that the last mineral is positioned underneath the Sydney Opera House. How
