Monstergran

With her curly grey hair
and her old-lady clothes
be decidedly careful
not to get up her nose.

For, behind the kind smile
and the twinkling eyes
lurks a wicked old monster
who is thinly disguised

as a dear little granny
with long skinny arms
and a baking-bread smell
but under those charms

there's a monstrous creature
hiding beneath
with a huge appetite
and long, yellow teeth,

who can suddenly change
and turn really nasty
so, best not upset her
or you'll finish, a pasty.
