Hoot and Toot are double ended shunting chuggers. Hoot gets fed-up of Toot always being at the front, so Toot agrees to let him lead for the day. Hoot mixes up a delivery of red tomatoes and green apples. He also refills the spray shed with the wrong colour paint and Wilson is sprayed green instead of his usual red! Toot is upset with Hoot for getting everything wrong.
