This large adorable 17" Birthday Bear moves his mouth sways his head while singing, “Happy Birthday”.℗ The candle lights up and the bear blows out candle at end of song. Switch adapted to accept a standard 3.5mm switch, sold separately. Or users can press his paw to begin the fun. Press and release your switch to start, press your switch again while the bear is singing and he will stop. Great for teaching Cause & Effect.
