Create a haiku, nothing more to it.  However!  You are not limited to one haiku, you can create a few stanzas, so long as they're all in the haiku format.  But, you are limited to one entry.

Haikus (if you don't know) are poems with three lines, one with 5, then 7, and then 5 syllables.  An example is shown below!

Is all you will have to do
