Double Trouble

S3 E8: Llamas take over the streets in Arizona, making for one nerve-racking rodeo. An otter pulls a fast move on a hungry orca. A bull shark takes its chances around a gang of hippopotamuses. There are unlikely foes: a troublemaking dolphin strikes, a sea lion gets revenge on a thresher shark and a heron dukes it out with a rat. Predators do what it takes to survive, but fate can take surprising turns.
