Upon first inspection I had no idea as its so weird especially the cube like box.

I see bubbles...could it be Bubble Bath Bombs?

Obviously far too easy. Something like that - the instructions tell you to add one loco to 200 litres of hot bath-water. You do get a one short but genuine section of blue track though!

For a Bath Bomb the detail is great
