If someone discovered that they are allergic to an endangered species' dna, would continuously acquiring the animal in an effort to save the species be a feasible idea? Could the frolis maneuver be used to barf it a bit different each time?
OOooooohh, finally a good idea to come out of this horrible cursed headcanon. It's not 100% clear if you are allergic to, say, that one particular crocodile or to crocodiles in general. But assuming that it'd work with multiple crocodiles (or condors, or otters, or whatever) then you'd need one heck of a selfless morpher willing to endure several days of morph "burping" followed by an unpleasant morph "barf" to get a good population going. Still, it could be like donating blood: you could sign up to do it once every several months and get several donors going at the same time to create a steady supply.
