Ok before I hit the hay. You can turn into an animal at will. Your clothes and such won’t turn with you but mass is not conserved so you can turn into something much bigger or smaller. It has to be a real creature that does or has existed and I guess if you want a plant that would be fair game. For me its an albatross. could travel around the world. might even manage to carry something that is not to large if packaged right. I am a bit torn though as the ocean is large so maybe a sea creature would be better. like a killer whale. of course then its not great for getting somewhere inland.
Migratory bird of some sort. I’d go with a species that dies migrating the least often.
you know someone said the artic tern and I had considered it but the albatross seemed more efficient but I see the albatross is not as good over land. I just found out sea birds have a gland that let them drink salt water to. So im leaning toward the artic tern now.
Nice, I’ll go artic tern they look sleek like the F1 of birb.
