The TARDIS lands on the buckyball ship. Everyone grabs a flashlight and goes for a look. The Doctor takes note of all the spider webs (and concomitant spiders) and muses that you don't usually find such things in space. He finally notices Brian and starts railing at him for stowing aboard. "Doctor, that's my dad," Rory says. Clowny music plays. They eventually get everything sorted out and Rory explains to his father that all the "traveling" he and his wife have been doing has actually been through space and time. In a police box. Brian is too stunned to react.
As they begin exploring the ship, Amy chastises the Doctor for disappearing for 10 months. She worries that Nefi and Riddell are the Doctor's new companions. The Doctor assures her they're new and he hasn't replaced the Ponds. Something big thuds nearby. Everyone follows the sound to a large elevator. When the doors slide open, two ankylosauruses lumber out. Don't you hate when you get on an elevator and it's full of armor-plated dinosaurs? Ugh. Most of the gang flees to safety, but the Doctor just stands there grinning in wonder. "Dinosaurs! On a spaceship!" Amy finally has to grab him.
After the opening credits, everyone runs through the dusty ship and ducks behind a wall to escape the dinos. Riddell whips out a knife and offers to kill one of them. The Doctor nixes that idea: "We just found dinosaurs! In space! We need to preserve them." Riddell scoffs. "Who's going to preserve us?" Eventually the ankylosauruses galumph past and the gang is left to wonder on just whose ship they've landed. Someone or something is watching them through a computer screen. "Intruders detected," the screen tells us. "Are you saying," Brian asks, "that dinosaurs are flying a spaceship?" The Doctor rolls his eyes. "Brian, please! That would be ridiculous. They're probably just passengers." Almost as an afterthought, he mentions the missiles that will be headed their way in six hours.
The gang resumes their exploration. The Doctor finds a computer screen, covered in spider webs and lush vines even though there doesn't seem to be much light to speak of. The Doctor looks through some schematics of the ship and says he needs to get down to the engines. He, along with Rory and Brian, are teleported in a flash of light onto a gray, windswept beach. Brian's had just about enough of all this sci-fi craziness and storms off to have a moment. "Is he all right?" the Doctor asks. "No, he hates traveling," Rory says. "Makes him really anxious." Rory notices that the beach appears to be humming, so the Doctor advises them to dig. Luckily, Brian happens to have a little folding trowel with him like it's the most normal thing in the world. He soon uncovers a metal floor beneath the sand.
