Ugly Gue

I was in the classroom hall,
And underneath the door,
I could see a sticky substance,
Lying upon the floor.

There right before me,
I saw a big slime,
About 6 foot tall,
Trying to do a mime.

It had a huge head,
It`s arms dripping with gue,
A strange type of colour,
I think greyish blue.

Wearing a baggy top,
With matching purple shorts,
Pulled up very high,
So I could see it`s ugly warts.
