plink

Hardly had the word "brigands" crept into my mind with an accompaniment of heart-beats something like the plink!

So the gnarble swam around inside, trying very hard to think, And while he did, his floppy tail was tickling the plink.

The gnarble almost made it to the surface of the sea, But the plink chomped down and swallowed him as if he were a pea.
