Our Deluxe Large 6″ Natural Frog Guiro is better than other frog instruments because of the construction, finish, and sound. The 6″x6″ size is large enough to create a realistic ribbit-like sound, like a croaking frog, when played correctly. It is also a low-range pitch as a wood tone block. INSTRUCTIONS: Use the wood stick (included) to gently rake up the frogs back to create a lower-pitch cricket chirp. Or lightly tap the nose of the frog with a thick end of the striker to get a resonating note as a wood tone block. Store the striker in the frog’s mouth. NOTE: This 6″ size frog guiro is large enough to be safe for younger children and strong enough to hold up to the rough handling of children.
