Wearing a green bandanna, My Piggy Piper plays a fun game and flaps his ears and sways his head to the songs "Farmer in the Dell" and "Old MacDonald." He has been adapted to accept up to 2 standard 3.5mm switches (sold separately) so people with limited hand function can make him play and sing. Press and release one switch to play an imitation game with Piper and the other to hear him sing. These functions can also be selected by pressing the buttons directly on Piper. This cute piggy is great for enhancing language skills, providing auditory and visual stimulation, encouraging movement, and teaching following oral directions. Marvin measures 12" tall and is unbelievably adorable and soft! 2 AA batteries included.
