Leeches

On the wet grass after rain you better watch out
For the little dark leeches are crawling about
For to get some of your blood to your legs they will cling
Whilst not life threatening to play host to leeches is not a pleasant thing
For whatever reason your blood they do need
And when they've drunk their fill the puncture mark on your skin does slightly bleed
In damp and warm weather they seem to multiply
And attach themselves to any legs to where they are nearby
If you happen to see one you are on leech infested ground
For they are not scarce in large numbers they abound
In that spot do not tarry from there move quickly away
For to play host to leeches will not make your day
On the wet grass after rain the dark leeches are out
On their search for a blood host they are crawling about.
