Create a minimalist illustration that captures the essence of playfulness with a focus on the slogan "Boss Baby!" The design should feature a simple yet vibrant depiction of a cartoonish baby character, styled in a sleek, modern way, wearing a tiny suit and a playful expression. Surround the character with a few essential toys, such as a colorful block and a small teddy bear, rendered in bold, flat colors like bright red and sunny yellow. The slogan "Boss Baby!" should be integrated into the design using a clean, sans-serif font, positioned above the character in a contrasting color to ensure visibility. The overall composition should evoke a sense of joy and simplicity, perfect for a toddler-themed project.
