A kitten made of hashes, hiding six secret words.
Each coloured line on the kitten is a different code: a number code, a backwards word, Caesar’s secret shift, Morse code, the pigpen cipher and binary. Each one is a bit trickier than the last. Crack all six and the first letters spell the password. The kitten even wears a Malicious Threads collar.
