There is a line of Nintendogs plush toys that I can't seem to find any info on, including on here.
I found this at a local thrift store:
And after some searching I only found two pictures of it online, one of which was an ebay listing featuring it in box and one of which was on the website for a company called Blue Square Innovations. According to the ebay box, it's called a "Wave and Play Pup". I asked about it on Reddit as well, on r/helpmefind, and apparently beyond those two pictures and one youtube video showing them in a Toys R Us there is absolutely no information to be found on this line.
It's partially robotic, with a button in one paw and what I assume is a wave sensor under the nose, and barks, turns its head, and wiggles its ears.
Does anyone have any further info, or even any of the other dogs from this plush series?
