This is unlikely however, as Spiker and Sponge are shown to have economic problems as their house does not look good, and they have very little resources, and the school of fish could’ve been the part that is just his imagination.

He has since been forced to live with his horrible aunts, Spiker and Sponge, who treat him like a slave, keep him in the attic and only feed him fish heads. It is also possible that the shark was built by Spiker and Sponge to bring James back in case he tries to escape, as when it rises out of the sea, it spouts several plates of the same rotten fish heads they tried to serve him the other day after it sucks up a school of tuna. When he was four years old, Jamess parents were gobbled up by a rhinoceros.The shark’s existence is unusual, as it is unknown how and why it was created or even if it was a figment of James’ imagination.It might also have been to make animation easier, as it would probably be very difficult to animate a bunch of sharks with stop-motion.

It is unknown why it was changed to a giant robot in the film, but it may have been to make a more compelling and intense scene than a group of normal sharks.
