Answer:
I tell people to be careful when handling boxes.
Without me everyone would lose their head. What am I?
I am the kind of food monkey likes and people slip on me and fall in cartoons.
I wear a green jacket on the outside white jacket as a second layer and red jacket inside. I am pregnant with a lot of babies. (one word)
I am in truth a yellow fork from tables in the sky by inadvertent fingers dropped the awful cutlery. Of mansions never quite disclosed and never quite concealed the apparatus of the dark to ignorance revealed.
As round as an apple. As deep as a cup. All the king's horses can't pull it up.
