Nothing screams ‘B-movie’ like giant, man-eating spiders. Just think about Ron’s face when he first clapped eyes on the Acromantula of the Forbidden Forest. It was, understandably, ‘livid with terror.’ Hairy, monstrous and as big as carthorses, the many spidery children of Hagrid’s pal Aragog each had eight eyes, eight legs, gigantic pincers and an appetite for human flesh. Cute.

Arguably the most terrifying of all Hagrid’s pets, (which includes an actual dragon, lest we forget) the ageing, blind Aragog had lived in the Forest since the first opening of the Chamber of Secrets forced him to flee Hogwarts. When Harry and Ron paid him a visit many years later, Aragog was surrounded by his wife and children and he has a lot of mouths to feed. A lovely, happy, hairy, scary spider family.

Harry and Ron were only saved from becoming lunch by the unexpected reappearance of Mr Weasley’s Ford Anglia. The car got them out of the woods, but the thought of being surrounded by hundreds of huge, hungry spiders is hard to forget.
