(Series 15, Episodes 5-8)
Summary: Not wanting to nit-pick, but the enemy is pretty visible, tbh – it’s a giant asthmatic prawn on wheels. Teeny tiny Doctor and Leela clones play a game of cat and mouse inside the Doctor’s brain and people start shooting lightning bolts from their crazy silver eyebrows. The Doctor tries to come up with a clever solution but it all goes wrong so he just blows everything up (as Leela suggested in the first place).
Watch it because: “K9 is my best friend!”
