It always turns out that the wish goes wrong in the dream world, much to the character's disappointment. The character then complains again with another 'if only...', which automatically stops the dream. From the dream, the character learns to be careful with what they wish for, and then decides that instead of changing the real-world situation to their will, they should simply leave it as it was and find a way to have fun with it. All the Rubbadubbers are then happy again. Each episode ends with Reg the robot, one of the Rubbadubbers, announcing to the others that Benjie and Sis are arriving for their bath. The toys then excitedly prepare themselves for it.
