Once again, turning to the Tardis Data Core for inspiration…
4×02 Legend of the Cybermen: The Doctor takes Sammy to Mythtopia, the greatest amusement park of the second Great and Bountiful Human Empire. But this playground of fantasy has become terrifyingly real: King Arthur searches Atlantis for the Holy Grail while Beowulf enlists the help of Count Dracula to defeat the Loch Ness Monster. But the greatest danger lies within the “Aliens Invade” attraction, where a long-extinct enemy from humanity’s past is being resurrected, and is intent on giving Mythtopia a deadly upgrade.
