And you thought your feet were just for walking! The World's Largest Piano Mat spans a massive SIX FEET wide and is powered easily by 4 'AA' batteries. Made of a durable and easy-to-clean plastic, the floor piano folds out and allows you to record your own song, or play along with a pre-installed recording. Piano not your thing? Then choose from a variety of other instruments, including saxophone or xylophone. Yea, xylophone! Create your own tune with just your wit and your little piggies, and record it. Or try out some kung fu or B-Boy moves, just to see what you can construct. The World's Largest Piano Mat can handle it; can you?
