The bears' cottage is shown as a 4x5 grid. Three bears (brown=9) leave the cottage — their cells go to 0. Then Goldilocks (yellow=7) enters and disturbs items: she sits in chairs (changes some furniture cells from 8 to 0), eats porridge (changes 3 to 0), and sleeps in a bed. In the masked grid, the bears return home to find Goldilocks asleep — all three bears reappear at the entrance while Goldilocks (7) is in the bed position.
