This is an early model of Pikalmin that I purchased on Yahoo Auctions about 20 years ago. The battery case shows no sign of leakage. The voice speed change via the stomach knob has been confirmed. The shot output via the red button below it has been confirmed. The output from the three nuts on the face and the sensor on the tongue has been confirmed. The three-stage change of the switch on the left foot (facing forward) has been confirmed. The eyes and cheeks also lit up properly in time with the sound. The batteries used for testing will also be included. I don't remember all the functions, so please bid if you are okay with the above confirmed points. Since this is an old item, please understand that it is non-returnable and non-refundable. - Color: Yellow - Function: Music playing function - Design: Three-dimensional character shape - LED: Equipped with red LED lights - Control: Dial-type volume adjustment - Back design: Striped pattern - Material: Plastic Thank you for viewing.
