At the Gloom and Bloom dance, The Corpse Flower blossoms and reveals not just a bloom, but a ghoul, Amanita Nightshade, a long-lost frenemy from Cleo de Nile's past.
The story returns to where the last episode left off, with Lagoona returning from her trip to Madread early to attend the dance with Gil, only to find him dancing with Lorna. Gil and Lorna attempt to explain, but Lagoona runs off in tears. Gil chases after her, while the other students realise the Corpse Flower is about to bloom...
Gil finds Lagoona at the swimming pool, and explains he only took Lorna to the dance as a friend to help cheer her up. Lagoona apologizes for making a scene, explaining she had been looking forward to surprising him and watching the Corpse Flower bloom. Realizing there's still time, she leads Gil back to the garden.
They join the other students just as the Corpse Flower blooms open. To everyone's surprise, they discover a plant ghoul is resting inside the flower. To Cleo's horror, she recognises the ghoul as Amanita Nightshade.
Amanita is delighted that the dance in thrown in her honour, and she recognises Cleo in the crowd. When the others ask if they know each other, Cleo angrily admits that she knew Amanita when they were 'tombmates' together long ago. Amanita laughs and calls Cleo a wallflower without a date, but Cleo introduces Deuce as her boyfriend. Amanita immediately takes a liking to him, and drags him away for a dance, much to Deuce's confusion.
The night ends with Lagoona and Gil sharing a slow dance, while Cleo and Amanita both fight to dance with Deuce.
