The quality of these toys will blow you away. Beautiful design, top quality silicone, really easy to use controls and a whole range to collect. What more can we say? This Dolphin comes in a gorgeous pink colour and, like all Fun Factory Generation II toys, has a rotating dial at a set-off angle that allows you to control the vibration frequency with one hand. One day all toys will have the same quality finish as this. Requires 2 x AA batteries (included)
