Answer:
I go up when the rain comes down
I sit in a corner while travelling around the world.
Flat as a leaf, round as a ring; have two eyes, can't see a thing. What am I?

What do you call a bear in the rain?
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
