Kalimba with built-in sound recorder and player. While acoustic properties of Zoots are far from top notch, the ability to record playing "right here, right now" - with one button pressing and to play them through own speaker, changing speed on the fly (slower/faster), maximizing cartoon-style sound, opens up a lot of creative possibilities for this toy.
Incredible funny thing!
And for most serious players there is audio output 3.5 jack.
