This is a Sonic plush that's also a bluetooth speaker?
It's a bit of an odd combination, a doll that you can use to play music? But...here it is, in its 'chibi' little-big-head style. As you can see it comes in a modern style branded box with the logo on top and CG portrait on the front. It's a nice box with plastic window & features listed across the top (for how to connect it/what it does)
However....
The plush itself is classic, so that's a modern vs classic mis-match (which sometimes happens) but then, is it supposed to be Movie Sonic? The arms are blue which is a mistake with everything other than Boom or Movie. That's 2 incongruities that make this sort of strange or almost suspicious.

Look at the texture on the shoe-soles, that's probably where the sound comes out. You can see he also has a paper tag by looking under the hand inside the box. "Bocina" is Speaker in Spanish. Other than the mistake packaging and blue arms it looks like it's well put together with 3D spikes, consistent 'chibi' style and good embroidery. 

...And, here's what it looks like out of the box.
It actually comes across a little wierder outside of the box. Here, you can really tell that somehow the shoes ARE also the legs? There's not even the 'sock top' in there or anything, they're just...his legs. Also that they're coming directly out of the 'belly dot' area doesn't help them. The spikes as 'one flap off to the side' is a way to stylize the head and make it simple, so they've gone with that.
At the bottom, you can see they of course deleted his back spikes but left the tail. The plastic plate area is where the electronic inputs would go like a USB stick of music or maybe a memory card to plug in. It's a wierd, off-model item to be sure. These are factory photos.
