Unmorph immediately after exiting the tunnel while still descending, to continue chaining temporary blue. The frame window for the unmorph depends on the alignment of Samus' bounces. Even if Samus bounces upward out of the tunnel, it is possible to unmorph and use a pause buffer to remorph while retaining blue.
