Help the Hermit Crab Find the Shell — Level 3

The most forked page in the series — 19 dead ends branch off a 75-square route, a false turning for roughly every four squares traveled. A hermit crab hunting for a shell is a fitting excuse for it, since trying one and rejecting it is what the animal actually does.

Hermit crabs have soft bodies and borrow empty snail shells for protection, moving into a bigger one as they grow. Sometimes several crabs line up by size and swap shells in turn. Trying a shell, deciding it does not fit and moving on is exactly how this maze works: try a branch, back out, try the next.

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