My sister will be having her O levels examinations thus I gave her a stress-reliever toy. I told my sister to figure out herself on how to work the toy.
It is called the Unazukin.
If you talk to it, ask him questions, he will reply you by nodding his head or shaking his head.
So sister, if you haven't figured it out yet, that is how it works. You need to talk to it.
