Here's a sort of interesting backpack. It has the usual "Sonic the Hedgehog with Attitude" catchphrase that UK area items love to use, but the front of the bag is sort of designed as a loop, checkered with Green Hill's signature ground. It's a bit off center, and there's no grass, but you can see little Eggman & his checker wrecker flying by. Sonic, however, looks annoyed/tapping his foot, which is also somewhat uncommon. The edge of the bag likely has another Sonic graphic.
