No, wait, I want to go this way... no, I think we should go this way... this way, this way is the way I’m pointing it’s the best way... you’re all wrong, let me show you which way to go...

Funny, but you are actually correct. The starfish has no central nervous system, just a nerve ring that allows the nerves in the arms to communicate with each other, so they basically argue about what to do until one arm dominates the others and then they follow along.
