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. They argue and split apart, going their separate ways!

Toot complains that Hoot doesn't seem to be able to tell the difference between green and red. She learns from Irving that some chuggers can't because they're colour blind. Toot realises she's been really mean and it's not Hoot's fault. The twins are reunited and normality is restored as they begin to happily bicker once more! Show less
