Answer:
Four leaves I have.
I have three eyes and only one leg. Obey me or you will be sorry.
I'm tall I'm round and hollow Seems to get chewed a bit But you'll rarely see me unless the other end is lit.
I will disappear every time you say my name. What am I?
Squeeze me and I cry tears as red as my flesh but my heart is made of stone.
Give it food and it will live, give it water and it will die.
