Tobias is a rainbow creature. He thinks he's heavily built, but he's actually quite small, as shown in The Pressure when he couldn't even cut his skin with a stick. He's obsessed with sports and is always trying to find new ways to hone his physique. He can also be somewhat of a bully, as shown in The Quest , where he throws around Anais 's stuffed animal, eventually dropping it out of the moving bus. He is also greedy as shown in The Third , where he charges Gumball and Darwin twenty dollars for his friendship.
