Swedish musician Mattias Krantz set out on one of his most unusual experiments yet after rescuing a young octopus from a live fish market and naming him Takoyaki. Fascinated by octopuses’ intelligence and independent arm control, Krantz attempted to teach Tako how to play piano, testing everything from modified keys to visual cues before realizing traditional methods wouldn’t work. The breakthrough came with a custom-built “crab elevator,” a reward system that lowered food incrementally with each correct note, forcing Tako to complete an entire melody before earning his treat. After months of trial, failure, and persistence, the pair eventually began playing simple duets together, marking a strange, funny, and oddly touching fusion of curiosity, engineering, and interspecies collaboration.
