Strange things are happening at an English boarding school called House of Anubis. Popular student Joy goes missing, the school's cranky caretaker has a creepy stuffed crow and the school's attic may be haunted. When recent American transplant Nina gets thrust into the school during this time, she decides to investigate along with her new friend, Fabian, and housemates.
Nina and Fabian puzzle over the mysterious cube that they found in the tunnels. But it falls into the wrong hands and soon Jasper steals it for the Collector. (S2, ep 17)
Nina works out how to make the mysterious cube into a key to unlock the first door in the tunnels, and the Sibunas face their next task of deadly booby traps! (S2, ep 18)
The Sibunas' next task is a deadly Egyptian version of hopscotch. If they get the sequences wrong then the ceiling starts to descend. (S2, ep 19)
The gang figures out the safe sequence to cross the deadly hopscotch. Then, when Nina hears Senkhara calling, she follows - but is she walking into a trap? (S2, ep 20)
Amber, Nina and Fabian have had the same dream of the spirit pushing Nina into the chasm. While Joy organises the ball, Vera and Trudy have a bake off. (S2, ep 21)
Amber, Nina and Fabian complete the hopscotch challenge but there's a bigger test to come. Eddie gets Patricia into trouble over the music, then saves the day. (S2, ep 22)
The Collector creeps into the library, leading to a close shave for both Nina and Victor. Jerome and Alfie bet that Eddie can't get Patricia to dance. (S2, ep 23)
Nina flees to the tunnels, while Jerome reads the letter his Dad sent to Poppy. Nina is angry with Fabian, but shows him and Amber the crocodile beam they need. (S2, ep 24)
Jerome reads that his dad wants him to visit. Patricia softens towards Eddie, then finds out about his bet, while Joy and Mara sign up for the school website. (S2, ep 25)
The Sibunas need to practise laying the beam. Victor finds the lock and the map of the tunnels. Alfie fails to dump Amber. Patricia plans her revenge on Eddie. (S2, ep 26)
Victor and Vera hide in the cellar and see Nina entering the antechamber code. As the Sibunas practise dodging pendulums, Patricia's revenge backfires. (S2, ep 27)
Victor has been blinded by the beacon flash. The Sibunas only just manage to avoid him. Poppy's father wants to arrange a visit, but Jerome didn't tell her. (S2, ep 28)
Victor's sight returns in time for him to find a passage on the Mask of Anubis. Jerome goes to visit his Dad - but he finds that Poppy has beaten him to it! (S2, ep 29)
Amber tries to rescue Alfie from the tunnel. She fails and Fabian has to save the day. Later Amber and Alfie break up. Victor spots the amulet on Amber's neck. (S2, ep 30)
Victor explores the tunnels but reaches a dead end. The Sibunas plot to get the amulets back from Victor. Jerome's father has an important mission for him. (S2, ep 31)
The Sibunas plot to keep Victor awake so when he does fall asleep, he will sleep so soundly they can remove the amulets from his neck. (S2, ep 32)
Jerome tells Mara about his dad's impossible mission - but then Mara finds an important lead that may just help. (S2, ep 33)
Nina manages to find the release mechanism to open the next tunnel. It is a giant web filled with venomous threads - which Alfie discovers the painful way. (S2, ep 34)
Amber gives Fabian advice about Joy - should he take it? Alfie's goose eats Jerome's dad's gem and Vera and Victor plan to have a copy of the spare amulet made. (S2, ep 35)
Trudy shares her suspicions about Vera with Mrs Andrews. Meanwhile, Victor and Vera succeed in swapping the spare amulet in the dollhouse with a fake one. (S2, ep 36)
