Underdogs, a five-episode series narrated and executive produced by Reynolds, showcases animals on the very base level of the food chain, the kind with "bizarre mating strategies, surprising superpowers, deception, dubious parenting skills and gross-out behaviors," per Nat Geo. This will be stuff you've never seen before - on Nat Geo or elsewhere - like a cave in New Zealand that "glows brighter than a bachelor pad under a black light thanks to the glowing butts of millions of mucus-coated grubs."

Harry Gregson-Williams composed the show's music - that's nice. But somehow, Reynolds got Green Day to write and record the show's theme song. Naturally, it rocks.
