- You may be looking for Sonic the Hedgehog Adventure Gamebook 3: Sonic v. Zonik, the third Adventure Gamebook published by Fantail.
The story takes place in the zones of Sonic the Hedgehog 3, but features an original story involving Robotnik stealing all of the colours from the Floating Island. For this reason, some pages in the book are partially or entirely black and white. As with other gamebooks in the same series, the readers do tasks at the end of each double page to determine which page they will go to next. Tasks include counting Rings, Chaos Emeralds and other such items.
