Illustrate a vibrant and minimalist design featuring the slogan "Boss Baby!" alongside a cartoonish representation of a baby character. The baby should be depicted in a playful pose, with a few essential toys like a toy car and a building block placed strategically around it. Use a limited color palette with bright, flat colors such as blue, green, and orange to maintain a clean and modern look. The slogan "Boss Baby!" should be displayed in a bold, minimalist font at the bottom of the design, ensuring it stands out while complementing the overall playful theme. The design should convey a sense of fun and simplicity, ideal for a toddler's environment.
