I like entry #6, add some color, and change the font of Snack attack to have more action.
I love the ninja character of Entry #4, how about him attacking actual logo, maybe attacking the S, and slicing the S in half. Or a similar concept to that.
More of the characters attacking the logo. Keep the ribbon on his head black please. I like the font for example #32, but do not like the background for #33. Maybe change the font for example #35, and add more dramatic blood splatter.
