Feeling Hungry?

You enter the cafeteria and are bombarded by smells. The combination of food accommodating both human and robotic students makes for a less than pleasurable aroma. Despite it being a little after noon, the cafeteria is almost empty. Only a few students are scattered throughout. A massive purple titan is eating an amalgamation of gears sandwiched between two hubcaps. He has to be one of the larges robots you've seen since you arrived at the school, and his height is only extended by the horn protruding from his forehead. A few tables away, another robot, not quite as large, is reading a book and taking notes. He is colored in red, blue and yellow, and stands out against all the dull books in the library. Who do you want to sit with?
