a train on a track, or a ship on the sea, or a rimble-rumble rocket on a jolly journey.
Don’t forget your bag of raisins! Don’t forget your rubber bands! Don’t forget your flashlight and DO NOT forget your hands.
You’ll need ALL of these to travel. Put them ALL into your pocket for your shimble-shumble ship or your rimble-rumble rocket, for your trimble-trumble train or whatever those boxes are:
you are going on a journey and you might go very far!
