The Academy shuts down when a human spy is discovered inside. From Ickis' hiding place, he realises he has dropped a drawing of The Gromble in the hallway. The spy picks it up and accidentally drops his own secret document. Ickis, Krumm and Oblina use the paper to track down spy headquarters and arrange for a transfer of the documents. The Gromble is in love with the Library Monster, and he's not as strict as he used to be. Ickis is thrilled and wants to make sure that The Gromble stays in love, but The Gromble is unsure how to behave with a lady -it's been so long- so he asks Oblina for helpful hints.
