Here are the "OK" and "NG" versions of the capsule toy Pinpon Boo mini. When it's OK, the button on top lights up red. It makes a "Boo" sound (short), but the "Pinpon" sound only comes out as "Pi"... I think the batteries are dead, but I don't know how to replace them, so I'm selling it as is. It's about 10 cm long and 1.5 cm thick.
