TRIFEXTRA: Three Billy Goats Gruff

My first dinner. Gone.

There's something better trotting.
My second dinner. Gone. 
Something better I'm soughting.
My third dinner. Gone.
Such a gluttonous loss.
I rescind my intimidating existence,
living on bridge moss.

This post is in response to Trifecta's "Trifextra" weekend challenge:

We want you to take a famous story, poem, book, or fable, and retell it in exactly 33 words.  Feel free to change the characters around, twist the plot, interpret it in a new direction, or parody it, but try to leave it still somewhat recognizable.
