If I had my own line of cereal, I would call it Sweetums. It would have bits of chocolate in it, as well as other goodies, like marshmallows. I might even have miniature cookies in it. Basically a very sugary cereal. I would have a mascot and it would be a very cartoony fox, or even a cartoon beetle. The box would be averaged sized and have a blue backdrop with the fox standing next to a bowl, pouring cereal into it. The title, Sweetums, would be at the top of the box in big, bold letters, just like the cereal boxes you see in stores today.
