Eustace is a pretty interesting character, he does have a few sweet moments but his upbringing shows that if you are taught through cruelty, cruelty is what you know
Remember, you are you, not a character, you shouldn't have to fake a persona to get people pay attention to you, tell jokes you think are funny, give advise you think is great, vent about your troubles, it's better to have a few genuine friends than a crowd that doesn't know you for real
Who wins? The Flash, Quicksilver, Sonic, Shadow, Superman, all the F-Zero machines, Speed Racer, Dash, Roadrunner, Speedy Gonzalez and MKWii Funky Kong vs a tortoise that is the star of this story that teaches a moral?
