Mateusz, the academy's talking starling, was once a prince. The transformation left him able to pronounce only the endings of words, so Kleks and the boys must reconstruct every sentence he says. The episode shows a rescue that preserves life at the cost of identity and full speech, with the survivor dependent on others to be understood.
Filip the barber, Kleks's secret rival, builds a lifelike mechanical boy, Alojzy, and places him among the pupils. Alojzy mimics a child perfectly but has no conscience. The case shows an institution built on trust and play undone by an insider who imitates membership without sharing its values.
Each night Kleks gathers the boys' dreams and studies them in the morning, treating them as material to read and interpret rather than private noise. The mechanism treats inner imaginative life as usable information about a person and their future.
The academy is named for a blot, and its lessons turn accidents into making, such as reading figures in ink blots or mending broken things with whimsical improvisation. Errors and damage become starting points for imagination rather than failures to be corrected. Seen this way, a school's job is to teach children to transform what goes wrong, not only to avoid it.
