A vibrant, cartoonish cereal box design titled 'Nefario-s', featuring Dr. Nefario from Despicable Me as the quirky mascot. Nefario is standing proudly in the center, grinning with one hand on his hip and the other holding a spoon, ready to dive into a bowl of his signature cereal. He’s surrounded by his minions, who are happily scattering minion-shaped cereal pieces around in excitement. The box has bold, playful typography with fun, exaggerated fonts for the 'Nefario-s' logo. The color palette is bright with yellow, orange, and purple, with cartoon explosions and stars surrounding the characters. At the bottom, it says, 'Now with Extra Minion Power!' and 'Scientifically Delicious!' in a fun, childlike font. Over-the-top cartoon style, bold colors, vibrant illustrations, with some comedic action. The background is a zany laboratory setting with bubbling beakers and gadgetry. The cereal box sits atop a lab table.
