Octopus Vs. Octopus

Octopuses (which is just as legit a word as octopi) have all sorts of different traits.
Some grow big and scary to ensnare their prey with their large testicles tentacles. LOLz.
Others are small and nimble, and can even run on land (sort of) to escape their predators.
So… big octopus versus little octopus… who will win??
