Toy identification

Hello all! Lord Strange hopes all is well with everyone! If it please you this one would ask for your help with identifying the following toy. Lady Strange and this one found this after our son moved out. We believe it may have belonged to a past partner of his. He wasn’t interested in getting it back so we decided to give it a good cleaning and adopt it.

That said we’ve been unable to locate the charger for it and we’re hoping to learn exactly what this toy is called and what type of charger will work with it.

If you could please take a look at the following image Lord and Lady Strange are hoping someone can help put a name to this device.

Thank you so much!
Lord Strange
