This sound maker imitates the sound of the frog. It originates from shepherd’s toys. Shepherds would make them for fun when grazing cattle or sheep. They used to make it from walnut shell and horse tail string and wooden stick. It can also be used as a ratchet noisemaker.
How to play? Hold the stick in one hand and the wooden shell in the other – then stretch the string and rotate the wooden shell on both sides (right and left). You can also just hold the stick and rotate the wrist to make the rattle sound.
