Rob and Rex Prevent a Poaching

Nine-year-old Rob and his black lab Rex find adventure when they discover a wooden box hidden under the park gym in Rob's back yard. The box contains a small carved elephant, a map of Africa, and a new smartphone. What could these clues mean? With a tap on the phone's screen, a tiny blue dot becomes a tunnel, and Rob and Rex find themselves in an African animal preserve. Greedy poachers have their sights on a mother elephant and her baby, but Rob and Rex save the day.
