Zero is an octopus. Normal octopuses have eight arms. Zero has, well, zero. But that's OK because his friend Hero (who escaped the deep fryer on a cruise ship and is now, technically, a fish stick) is going to take him to a magical place where there is an endless supply of material to create new octopus arms, shark fins, and anything else you need. It's all plastic. It's all fantastic. It's Plastic Fantastic!
Except it doesn't quite work out as they had planned.
