Last Train to Cashville (S02E12)

Investigating a little boy's lost toy train, the "tracks" literally lead to a pet store, where Fat Cat and his gang are plotting to rob the bank next door, by replacing real gold bars with gold painted bricks transported by the stolen model train. Dale complicates the case by sleepwalking, after staying up the night before to watch the Late, Late, Late Show. He is left behind by the other Rangers who are captured when they sneak in to investigate. Dale wakes up and with the help of Zipper, frees the other Rangers using a scheme he saw on the television program. (iTunes)
