While the rest of Toad Kingdom was in panic over the missing Princess Peach; Encyclopedia Brown knew it had to be none other the Bowser who performed the kidnapping. While Bowser told Mario he was vacationing at Dinosaur Island during the birthday party Encyclopedia noted that the gas tank in his flying machine was full, and if he had traveled from Dinosaur Island directly to the castle as he said he had the tank would have been close to empty. Encyclopedia confronted Bowser with this fact and he quickly confessed and admitted to holding her in the dungeon while waiting for the sun to set so he could sneak her out. Princess Peach was rescued and made it back home in time for her Birthday Cake.
