Animated short set in a Lego version of the dinosaur theme park Jurassic World. In order to boost attendance, park founder Simon Masrani (voice of Sendhil Ramamurthy) asks the park's geneticists to create genetically modified hybrid dinosaurs - the latest product of their experimentation being the Indominus rex. But when their new creation escapes from its pen and begins terrorising visitors, it's left to park staff member and dinosaur trainer Owen (A.J. Locascio) to clean up the mess.
