One More Time is the 5th episode of Season 1. It originally aired on 20 October 2006 and was released on DVD volume 2
Four, Five, and Six have a jumping competition in the Gym, but Four doesn't want to do difficult tricks. Then the alarm goes off, and Agent 53 reports the problem of the train set; it starts with one cow on a truck, but when the train goes under the bridge, it becomes two cows. Four likes trains, so he is going out.
After landing on Platform 4, Four sees another problem; another truck with two sheep goes under a bridge and becomes three sheep. Then three horses become four horses. Agents explain that whenever something goes under a bridge, one more of the same thing is added.
Four takes a ride on the train. Three guesses that there'd be two number 4's, but is proved wrong. When Four goes under the bridge, he turns into a number 5, a number that's one more than 4. Agent 68 finds another Numberjack near a bridge in the park. That Numberjack is Number One! She's been making one more to everything every time they go under a bridge. Blue 5 has to stop her doing this, without having time to turn back into 4.
Five gets Blue 5 to stop some people going under the park bridge before it's too late. Blue 5 jumps up and scares away the woman. He tries to do it to the man, but it's too late! The man becomes double, and the two identical men are fighting with each other. Then Four turns into a 6.
Agents suggests to make the bridge the opposite of one more. Three starts up the Brain Gain and commands everything to be one less. Blue 6 scares away the two men, now turning back into one. One and Blue 5 come to the train set, sorting out the problem, and Four returns to being a number 4, and they both come home.
Back in the Gym, Four successfully does a jumping trick. Then Five asks the viewers if they'll find a number that's one more than 5 or one less.
