Arachne is a minor antagonist in Flushed Away: The Video Game. She is a huge Brazilian spider who dwells in her lair deep in the sewers of England and is the mother of all of the spiders in the area.
She was voiced by Miranda Robinson.
Originally from Brazil, Arachne had had many husbands. After eating one of her husbands, Edmundo, Arachne was overcome with indigestion and fell asleep with her children in a banana crate, which then somehow made it into the London sewers.
Missing her home, Arachne attempted to recreate it with Christmas lights and random objects in the sewer. One day, as Arachne was cleaning her quarters, Roddy wandered in and Arachne closes the door behind him as she complains about the mess her children made. Arachne explains her past and her lifestyle to Roddy and the rat tries to leave, but Arachne insists on having him over. Arachne suggests on having dinner and Roddy asks her what they're having, but Arachne grins at him and Roddy realizes that she's having him as dinner as she approaches him.
Using her need for tidiness to his advantage, Roddy threw Arachne's eggs around, causing the spider to constantly try to pick them up.
While she was distracted, Roddy would beat the spider down with his toothpick. Eventually, Roddy defeated Arachne and, on his way out of her lair, found another toothpick resembling a sword. Pulling it out of an olive, Roddy held up his new weapon in triumph.
Arachne is the only major character in Flushed Away who does not appear in the film.
Arachne's tendency to eat her husbands is an allusion to real-life spiders who do the same thing.
