Tux droid sings!i bought this from kysoh. he was around $150. but we returned it. and then they sent it back. so he was free. my dad thought it was too hard. he didn't give me a try. when we got at the post office , they where just about to throw him out (dead mail place) i was hugging the box... when i got home, i solved it. a stupid coin battery was put in wrong.
