Vibrating Rubber `Luv' Duck is £4.99 delivered from Play.com
Good price inc delivery from Play.com and is sold at IWOOT & Prezzieplus for £7 + p&p.
Here is the cheeky description : I may be plastic, yellow and float in the bath but I'm not just any old rubber duck as I've a special extra trick under my wing. Press my back and I vibrate very discretely and quietly enabling me to massage the parts that no other rubber duck has ever reached before.
I will give you a whole new experience at bathtime and I'm a sure winner with the ladies. The pleasures in the Duck, but what you do with me is of course entirely up to you. As a Duck I'm a pretty unique gift idea.
