Wearing a green bandanna, My Monkey Marvin plays a fun game and flaps his ears and sways his head to the songs: "Apples and Bananas" and "Five Little Monkeys." He has been adapted to accept up to 2 standard 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 Marvin and the other to hear him sing. These functions can also be selected by pressing the buttons directly on Marvin. This silly monkey 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.
