Don't dig it up, don't tramp it down,
The wildflower purple crown vetch,
It's that they eat and that alone,
Potatomen from the planet Retch.
Many extra terrestrials here
Are tiny and struggle to survive.
Bamlards from Gliese five-eighty-four
Subsist entirely on baby chives.
Extra terrestrials like the Balleyes
From Venus can hardly be seen,
They're so tiny, and so specialised,
They live on the fumes from Windowlene.
