Wildlife explorers Wilfred and Olbert each want to discover a new animal and win the Nature Discovery Contest. One day, a butterfly that theyve never seen before flies in through the window, and they both set off on a hectic chase to follow it. They stumble through many different places, including the forest, the ocean, and the desert, all the while encountering hungry animals, an avalanche, and fruit that makes them shrink! Will they ever find the elusive butterfly?
