【How-to】What does croaked mean - Howto.org

Frogs can trill, chirp, scream, bark, grunt, peep, beep, cluck, croak, quack, whistle, bellow, and hoot. But their choice of sound depends on their intent. Frogs make different sounds for different reasons, for example, to attract a mate, defend their territory, or fend off a predator.
