KAZOO — five-cell route
Trace KAZOO through these cells: 1 at row 6, column 2; 2 at row 5, column 2; 3 at row 5, column 3; 4 at row 5, column 4; 5 at row 5, column 5. Reading them in order gives K → A → Z → O → O.
Start by moving up once, then turn right and continue right for three moves. The path therefore has one turn and two straight segments. It spans two rows and four columns, assigning the first five open cells and leaving 30 cells for the four longer answers.
Use the consecutive O letters as the quickest visual confirmation. Once the route turns right, it never turns again, so any extra bend means the trace has left the supplied sequence. Both endpoints have four open orthogonal neighbors on the raw board.
