Flanders and Swann had more animals yet in their bestiary.

"No-one ever wants to court a warthog,
Though a warthog does her best...
We know her These and Those are like Marilyn Monroe's..."

And I wish I could recall, exactly, the F & S salute to the Sea-Horse.
The male Sea-Horse watches over the young, instead of leaving it to the female. And so, his "horse-faced wife" makes the round of charity matinees, "busily doing goo - HOOOOD, busily doing good."

Liz the Squeak, good on you for recalling "my cross-eyed bear." there was also "the chicken hymn," which opened with "Foul I to the fountain fly..."

which reminds me:
that version of Glenn Miller's In The Mood with clucking hens!
