The SpongeTrons all greatly resemble SpongeBob with all of them wearing Krusty Krab hats.
They are the only three clones who appear in the episode. Their behavior is much like SpongeBob's, as they are clones of him. They are also best friends with Patron, and they love jellyfishing, as in the episode, they pulled out some jellyfishing nets and excitedly yell, "JELLY FISHING!" That is their only line in the SpongeBob SquarePants series so far, and it is most likely that they won't appear again. It is also most likely that they are able to fly like SpongeTron; however, they are not seen flying in the episode. They probably work at the Krusty Krab, and it's possible SpongeTron does since there descended from SpongeBob. It is most likely they are also SpongeTron's siblings too.
