Answer:
I'm the source of all emotion but I'm caged in a white prison.
I am an English word with 3 consecutive double letters.
Crooked as a rainbow and slick as a plate ten thousand horses can't pull me straight.
I am the black child of a white father a wingless bird flying even to the clouds of heaven. I give birth to tears of mourning in pupils that meet me even though there is no cause for grief and at once on my birth I am dissolved into air.
I fly when I'm born. I lie when I'm alive. I run when I'm dead. What am I?
I am a animal that is cute but dangerous, what am I?
