Finally Matt was done with the settings and climbed out of Hal, now a fairly small open cockpit biplane. He stood next to Jacob, facing the plane.
"Hal! Change into your Otter form!", Matt commanded. "Aye Cap'n", came the prompt reply. Jacob wondered, "Did you say otter?" and Matt replied, "You'll see".
Meanwhile Hal began to change, at first his cockpit started to close and fill up, then the vertical bars holding his wings in place shrunk and moved downwards. Eventually a split formed running from just behind his engine cover, which by itself was loosing its definition, almost all the way to the back. His form split up and the lower part, still having its small wheels split, splitting it into a left and right part as one in the back which was also still carrying the tailfins and rudders, a lot smaller than what he started with, though. Gradually his wings started to become rounder, almost cylindrical, and much thinner, eventually hands started to form on them. His engine, now completely deformed started to become more cylindrical, before even forming a face around the prop shaft and propeller that were still there. Gradually Hal's right leg formed a boot, while his left one still kept its wheel, forming a mechanical leg holding it. Just under his knees a pair of brown leather pants started to form, obscuring the point where the metal met the flesh. On his belt there were two holsters each carrying a pistol. From its back a thick furred tail extended ending in a much smaller version of his previous tail-fin. His upper body formed a leather jacket below which a set of ammunition belts formed. Below those there was fur. The jacket had four short sleeves from which 2 sets of furred arms grew, one above the other, each one leading to a fingerless glove. Then his face finally stared to form. his prop-shaft formed a not to pointy nose to which the rest of his face conformed, the prop moved further inwards and pointing downwards just like whiskers would do. Below a large mouth formed and the fur below that brightened up to conform with his brighter belly fur. Then his eyes formed, the right one becoming a sort of optics cleanly embedded in his head, while the other one turned into a slightly cartoony anthropomorphic eye. On his scalp a pilot's hat including goggles formed.
He would have been a rather imposing creature if he was perhaps a bit larger than his 4 feet, and wasn't an anthropomorphic otter-plane thingy.
Jacob laughed as he saw the figure, "You really outdid your self here", but suddenly found the barrel of a pistol close up pointing at his helmet. "What'll be it for him, boss?", asked Hal, and Matt replied, "Nah, leave him alone, he's part of our crew."
