The Whip-Poor-Willephant: Another Animalephant Amalgam -- With Coda

Whip-Poor-Willephants combine 
prehensile trunks with song. 
These crossbreeds’ noses…? Serpentine. 
Their chirrups…? Overlong. 

Mulephants ‘n’ Molephants 

be crossbreeds, ev’ry one.

I’ll add to that pair Volephants. 

And now I think I’m done.
