Our Deluxe Jumbo 8" Natural Frog Guiro is better than other frog instruments because of the construction, finish, and sound. The Extra Large 8"x8" size creates a deep ribbit-like, croaking frog sound when played correctly. It is also a bass-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 deep resonating note as a wood tone block. Store the striker in the frog's mouth. NOTE: This 8" size frog guiro is large enough to be safe for younger children and strong enough to hold up to the rough handling of children.
