Solomino

i am geussing that this is an update, but you used to be able to morph as soon as you killed a mob. You could morph back into it whenever you want. now, they dont appear in the place where you select morphs. Does anyone know if there is a way you can morph, unmorph, then morph again without killing the mob, or is that impossible. If it is impossible, what is the easiest way to fly?
