Here is an exercise: using the Jabberwoky as a form to copy and then put real words into the descriptive phrase.
Twas brilling, and the slithy toves
Did gyre and gimble in the wave;
All mimsy were the borogroves,
And the mome raths outgrabe.
Twas stroming and the orange clouds,
Did dash and break in the sky;
All huddled were the guinea pigs,
And the love bird yelped.
