[Tin Man]

i think the bomys should be able to buy "shells/egg forming stuff" that will alow them to "transform" and grow wings which will let them choose if they want to go up rivers at a casual pace and not the chaos that bomys have from swimming. You should be able to move faster while flying but not have the ablity to use weapons or items. And you could have the bomys make or buy different shells/egg forming stuff that would yeild wings that would have differnt colors,speeds, and slowing abilities.
