Help the Elephant Find the Water Hole — Level 3

The biggest animal in the catalogue with one of the longest walks in it — 83 squares to reach water. Seventeen dead ends is a lot to back out of on a route that length, so this is a sheet for a child who has stopped minding being wrong.

Elephants drink a huge amount of water every day and will walk long distances to find it, remembering where the water holes are from year to year. They also spray water and dust over their backs to keep cool. A long walk suits this animal, and the dead ends suit a child who has stopped minding a wrong turn.

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