The table here is pretty much just to set up a place for the other characters to watch the fight coming up. Magenta is trying to be a little classier, so a nice shaded table to eat at is a nice addition. Everyone is also excited about pizza, because it’s pizza. I guess she has vegan pizza for Red. Really all you need to do is take away the cheese and only use vegetables as topping. I know they make vegan cheese but I don’t think Red cares about eating fake cheese.
