John

John is the tertiary protagonist in the series. John likes to build with Legos (sorry, lEgO), and he's also a huge fan of Star Wars. John is best friends with Jacob, Mango, Spike, and Walter. He's very protective over his Lego creations, as seen in "John's Lego Collection" where if you touch his giant Lego stack, he'll go, "Hey! Don't touch that!" John is also really good at drawing, as so is Mango. John appears with brown spiky hair, similar to Jacob's hair, but with 3 spikes instead of one, with the outer two smaller than the middle spike. He wears a red shirt, and blue pants. John is based off of Jacob's friend in real life, sharing the same name.

John's first appearance was in "Butters' Dance Reanimated" where Alan dances in front of Jacob, Mango, and John, then Jacob says, "Butters (in this case, Alan), I hate you with every inch of my body."
