Mortimer Frog lived down by the creek,
Down by the creek he lived.
And he croaked by the creek,
Croak, croak, croak,
Down by the creek he croaked.

Mortimer Frog lived down by the creek,
Down by the creek he lived.
And he croaked by the creek,
Croak, croak, croak,
Down by the creek he croaked.

Cute!
What a fun poem. I’m interested in your use of the word ‘croaked’ and its literal and informal meaning.
