Grobes by Roald Dahl

From Charlie and the Great Glass Elevator
In the quelchy quaggy sogmire,
In the mashy mideous harshland,
At the witchy hour of gloomness,
All the Grobes come oozing home.

You can hear them softly slimeing,
Glissing hissing o'er the slobber,
All those oily boily bodies
Oozing onward in the gloam.

So start to run! Oh, skid and daddle
Through the slubber slush and sossel!
Skip jump hop and try to skaddle!
All the grobes are on the roam.
