This is the "Game On" backpack.
It is likely to be a Bio World item, as that tag seems to be their 2019 look. It's a standard size pack with 2 exterior pockets with zippers. The top pocket has the slogan "Game On!" with some stars in arches around it. The bottom pocket has a large (what is that, skeptical?) CG Sonic, with Shadow in the background. But, can you spot Knuckles & Tails? They're back there too, but they are busy blending in with the red & yellow background & star shape. The straps are a little more decorative than normal, they're blue with red edging. The side pocket flap has a character-montage of CG characters, including (probably) Super Sonic. This same fabric is used along the inner rim of the top-arch to the backpack. This is likely to be an Amazon item.
