Bigiggles Bruce the Blue Koala Bear Interactive Works Repeats What You Say. Bruce the Koala Bear giggles when you push his belly and repeats what you say in different funny voices. Turn him upside down and he screams "No!" Has a bobbling head. His bottom is magnetic. I do not have the platform so he can sit on your shoulder, but a regular magnet sticks. Measures approximately 6" tall sitting. Batteries not included. Please see pictures.
