"I'm a raccoon now?", you ask Jack. "Yeah, but not just a raccoon. I want you to stretch your arm out to the side horizontally.", he stretches his arm out for illustration and you do the same. "Now hold your hand vertically", he says and you do the same. "Now change it into a plane wing", he continues as you shrug in disbelief, "Just imagine your arm changing into a plane wing, I know you can do it." Suddenly it clicked mentally. It was like moving a muscle you didn't even know you had before and gradually your arm started to widen out and grow in size and weight resembling a plane wing more and more. Eventually it touches one of the racks and you pull back again making it gradually change into an arm again. You feel like in control over the whole process and although it is odd and perhaps a bit frightening, it feels comparatively normal.
Uncle Jack smiles as he gets a stool, "Now sit on that, and imagine your feet becoming the wheels of your landing gear." You nod and sit down. Trying the same technique you eventually manage to make the underside of your boots bulge out, gradually changing to the lower half of a rubber tire. Eventually the boots completely change into tires connected to your legs. You curiously try to rub one of them on the ground and note that it turns freely, until you realize that you can put on the brake and stop them at any time. You turn back one wheel and it gradually changes back to a normal foot as you try to stand up, skating along with the other wheel.
Uncle Jack has meanwhile moved some clothes racks around to create a larger space. "Now you better lie down here. It's time for your cockpit.". You nod and lie down on the floor awaiting instructions. "Imagine your body getting bigger and hollow with the cockpit forming inside. I know this is perhaps the oddest part, but I know you can do it", he said stepping a few steps back. You try accordingly and eventually you find the way making your torso expand like a balloon, while the rest of your body stays more or less the same. Your jacket seems to join with the rest of your body, forming a hollow aluminum tube, easily 150cm in diameter. On your back the material starts to bulge out and become transparent, until eventually it becomes a full canopy allowing sight into and out of your forming cockpit. Gradually all the instruments form, including the joystick. the padded seat also forms with a set of heavy duty seat belts. As the changes seemed to be completed you are basically immobile with your arms and feet barely able to touch the ground. Uncle Jack pushes open your canopy and climbs inside of you. You can feel his weight on your seat as he checks everything. "Good job" he says climbing out of your again, just before you start changing back, "To bad we don't have more space in here".
"So... can I fly?", you ask as you have regained your anthropomorphic form again. "Yeah, but we need more space for that and you still need to find out some details for yourself.", he said.
