#20: SURF'S UP, GERONIMO! Ah, there's nothing like a relaxing vacation on the beach! At least, that was the plan. But somehow, Geronimo's vacations never seem to go according to plan. Instead of a beautiful seaside resort, he finds himself in a fleabag hotel that is falling down around his ears! Will he ever be able to relax and enjoy his vacation?? #21: THE WILD, WILD WEST! Rat-munching rattlesnakes, is Geronimo excited! He is heading to America for the first time ever and Thea, Trap, and Benjamin are all going with him. They are going to visit a real ranch and go riding and herding cattle cowboy-style. It is sure to be the most whisker-licking-good adventure yet!
