Kids Logo?

Making a kids logo, and i felt that I'm not specialize in designing kids company logo. I failed and i just do my very best for the sketching and instruction book.

Which are the best logo i can pull off? (not really a logo for me, because i just took free FONT SPACE).
My lecturer told me to have a kid font in my logo and more colorful design for my product. Will try my best to finish it today. And post it tomorrow.
