The 3 little pigs

A very long long time ago,
there lived three little pigs,
who met a heavenly angel.
The heavenly angel told the three little pigs,
to collect one pebble each,
and she told them in these words,
"You'll be sad to look at them tomorrow."
The pigs were puzzled by her words,
and though reluctant they were
to collect the useless pebbles,
still they obeyed the angel's words,
for they are good dear little pigs,
The next day came and went,
they opened their pouches at night,
only to find that the useless pebbles have disappeared,
and in its place was a shiny diamond.
