This is the "Sonic & Friends Sticker Activity Book".
It's new in winter 2020. This is generally thought to be an Amazon item, but it may also appear in Barnes & Noble if they have a large enough kids section. You can see that the little disk there says "30+ stickers", and it also says 'activity'. However, supposedly it's only about 16 pages or so, that's very thin. And the activities consist of maybe like 3 pages of a maze, a word search and a crossword puzzle page.
So mostly, it's like a 7 dollar sticker book with...
About 30 stickers.
That's why there's no link here. (If it gets requested, it'll get added) but the value of the item just isn't all that high if it is so thin and there's only 3 activities in the entire book. Modern things usually have more value per dollar? Not sure what's going on here.
