After more than 20 years, here is another "Where's Sonic" search n' find type book.
The first one, styled a bit like 'where's waldo' came out in the 90s, and can be seen here on Gear too. This one though, arriving in 2020, has a much updated format with more to do. Not only will you get to look for Sonic who is hidden in deliberately complicated scenes on the pages, but there are other challenges as well. You can find friends too, as well as enemies, and certain numbers of things like "How many Chao" or "How many different wisps" that are also hidden around. So, this book gives more to do. It is composed of all CG imagry though, including the backgrounds and the characters. Most books like this aren't, so is that better or not as good as very-busy art? It's likely just a matter of opinion. This IS an Amazon item, and it is reasonably priced enough. You can use this link to go directly to it at Amazon (it is a Gear Affiliate link) Where's Sonic?: A Sonic the Hedgehog Search-and-find Adventure.
