A Bug's Life

OK, I am now about to be a sad Whovian bastard and list all the classic-era episodes set in London, with monsters. (This is also asking for me to overlook one, I know.)

An Unearthly Child (ep 1 only): no monsters (in ep 1 anyway)
Dalek Invasion of Earth: Daleks
The War Machines: The War Machines (well duh)
The Faceless Ones (if Gatwick Airport counts as London): Chamaeleons (but good luck finding a miniature for them)
The Web of Fear: Yeti
The Invasion: Cybermen
The Seeds of Death (part): Ice Warriors
Spearhead From Space: Autons
Invasion of the Dinosaurs: dinosaurs
Terror of the Zygons (the end): Skarasen
The Talons of Weng-Chiang: Giant rats and Mr Sin
Logopolis: no monsters in London
