Device Details


The switch adapted Cool Beats Penguin toy sings, dances, lights up and can be controlled with accessible switches that have a 3.5 mm jack. The penguin is a Fisher Price toy that teaches the alphabet, opposites, counting, and bobs side to side with lights and music.


To activate the penguin, the power switch must be turned on, which is located on bottom of the penguin. Once turned on, the assistive switches can be used as an alternative to the green and red buttons on the penguin’s feet for activation. The switch adapted toy would be beneficial for someone who may have difficulty pressing the original buttons on the toy. Some people may find the original buttons too hard to press, too small, or out of reach for appropriate use. If you don’t already own a 3.5mm jack switch, one can also be requested from the device library.
