- You may be looking for Sonic the Hedgehog Adventure Gamebook 4: The Zone Zapper, the fourth Adventure Gamebook published by Fantail.
In a direct continuation of the plot beginning in the previous book, the story takes place in the zones of Sonic the Hedgehog 3, dealing with the troublemaking Knuckles the Echidna. Instead of Dr. Robotnik stealing the Master Emerald as he does in the game, the doctor has stolen all of the Floating Island's colors. Thus, many of the pages in the book are left black and white, leaving the reader to color them.
As with other gamebooks in the same series, readers need to count rings, Chaos Emeralds and other objects to determine what page they progress to. This is unique from other gamebooks that have a reader simply pick an option and go to the page that shows the outcome.
