Marine Boy..... [No children harmed in this Blip]

.......Owen has always loved the water and has been diving, jumping and falling into water with gay abandon since he was knee high a grasshopper.
We took him along to swimming lessons from the earliest possible age and now thankfully he's quite strong; all the more important because he has absolutely no fear.

One worrying habit he has is 'swimming' around in the bath under the surface and he has recently started ducking his head under and pulling out the plug with his teeth when its time to come out. Mentalist!!

Does anyone remember Marine Boy?
