The Carpenter's Druthers (A Nonsense Poetry Composition Competition)

Who Carroll’s Carpenter Might Have Been 
Create an Alphabet’s Worth of Six-line Stanzas, Each Introducing a Different Partner for the Walrus   

Sometime in 1871, presenting the text for “The Walrus and the Carpenter” to his illustrator John Tenniel for the artist to illustrate, Lewis Carroll gave the man alternate choices for the character of the Carpenter, namely the Butterfly and the Baronet, explaining that each fit the poem metrically (in what is here designated as a -- ^ -- pattern) and that Tenniel should make the selection based on the chosen image’s pictorial potential. 

The list below features 26 other options Carroll might have offered. The list includes neither inanimate objects (for example, ‘the Catapult’ is not included) nor phrases (e.g., it excludes ‘the Bishop’s Thumb’ even though that phrase exhibits the requisite -- ^ -- pattern). Otherwise, pretty much anything goes, and the list is far from comprehensive.

Here’s Carroll’s original (with a normalized punctuation: pace Rev'd Carroll):
 

The Walrus and the Carpenter

Were walking close at hand;

They wept like anything to see

Such quantities of sand:

“If this were only cleared away,”

They said, “it would be grand!”

And here are several options:

The Walrus and the Astronaut

The Walrus and the Basilisk

The Walrus and... 

the Corporal, the Doberman, 
the Extrovert, the Fisher King, 
the Gadabout, the Harlequin, 
the Idiot, the Janitor, the Kittiwake, 
the Liberal, the Masochist, the Neonate, 
the Ombudsman, the Pantywaist, 
the Quietist, the Radical, the Shepherdess, 
the Trotskyite, the Ubermensch, 
the Vagabond, the Wanderer, 
the Xylocarp, the Yodeler, the Zebrafish

Or select your own new partners, as long as they maintain the -- ^ -- pattern.

Then compose six new line stanzas using each additional option in turn, following the metrical model and rhyme scheme of Carroll's original.
