Help the Fox Find the Burrow — Level 3

Going to ground: the goal is a hole the fox disappears into, which small children find satisfying in a way that an apple or a bone is not. Seventy-five squares and 46 turns place it squarely in the middle of the level 3 range on both counts.

A fox's home is called a den, often dug under tree roots or taken over from another animal. Foxes hunt mostly at dawn and dusk, and their hearing is sharp enough to pick up small animals moving under snow. The maze sits in the middle of level 3 on length and turns, so it is a steady test once the gentler sheets are done.

There is exactly one way through: no loops, and no square cut off from the rest.
