Here are 2 plush character backpacks. Instead of Sonic, who's had at least 2 'backpack doll' type things already, here's Tails & Knuckles. You can see a bit of a red strap there behind Knuckles. For an idea of the size, that's a blindbox Sonic figure ball dispenser below them. The plushes look pretty decent from here. How much are these, & where can you find / buy them?
