Again, the word doesn't change to match the joke, not even to make it fit the sentence better.

Unless you change the spelling of the words:

And my fine-feathered friend is a jolly toucan
And two can sound better than one toucan can!

And I'm going to have to take Alex' side in this, I've always been a little confused by the claws/macaws thing, caws/macaws works so much better.
