This is a great idea from Gemmy. This 4 foot durable nylon inflatable is just like the 8 foot outdoor ones but made smaller for indoors and contains no lights. This is the perfect size for those indoor sports gatherings. He sets up literally in seconds. Just plug him in and watch him inflate. He has a small powerful fan on the back of his feet that inflates him and keeps him inflated. Then when ready to deflate just unplug him and unzip the zipper. This is really a great item!
