RBFR Frog Guiro
Truly sounds like a frog!
A wooden frog with a ridge up its spine! Hold him by the feet, make a resonating chamber with your hand cupped underneath, run the large end of the beater over its spine and listen for the croak! Available in four sizes: 3″, 4″, 5″ & 9″. The larger the frog, the lower the pitch.
