Dinosaur Dilemma is the seventh title in the Nintendo Adventure Books series and the first to be based on the then brand-new Super Mario World, which it takes place shortly after.
 Plot Synopsis
The Story from the Back Cover:
Flying Duo Battles Koopa Clan
Mario and his new dinosaur friend, Yoshi, fly across Dinosaur Land to save Yoshi's homeland from the dreaded Koopa Clan. Bowser's armies have invaded the peaceful kingdom of the dinosaurs, threatening Yoshi's friends and family with total extinction.
As in all Nintendo Adventure Books, you control the action. Only you can make the choices that allow Mario and Yoshi to overcome the perils they face on the rocky shores of Dinosaur Land. Help them crack codes, solve puzzles, conquer mazes, and subdue enemies. Together, you must outwit a whole new collection of Koopa creeps-or go down in final defeat!
