In my universe there is a planet that harbors a super cell organism created by an ancient precursor species. If you don’t know a super cell is theoretical idea where the cell can do just about everything including seeing, eating, breathing, thinking and just about everything else you can imagine.
This super cell creature can adapt extremely quickly by rearranging itself to basically change its shape. When putting it into a different environment it while attempt to adept. For instance if it was tossed in water it could form flippers.
My question is: what would be the most effective form of transportation for this creature to use while on land? Would wings, legs, or tentacles be preferred? Please provide pros and cons.
Edit: Consider the creature has a significant source of food, energy consumption is not a concern. I am purely focused on the movement itself.
