R/C Bath Duck
Finally your yellow Bath Duck Radio can get a radio controlled friend.
The remote control duck lets you move him forwards, backwards, left and right, and a 45 second charge will have him swimming for 3 minutes. If you can bare to keep your hands off it for 5 minutes to charge you can get a play time of 15 minutes.
The R/C Bath Duck is yours for £15 (about $30 USD) from Red5.
