Is this a good idea for a children's book?

Go for it girl! Throw everything into the mix, a cute but clumsy baby mammoth, a giraffe with no neck or even a polar bear that's afraid of the sun in case he loses his color maybe he could use the turtle as a sun cap. It's all in the mind and kids minds are more open than us so called grown ups and they love bs stories as long as they can believe them.
