Bird in the peanut

I have a toy peanut. It is 15 cm long, 5 cm wide and 6 cm high. It is the home of two birds.

Open the lid and you will hear the two birds screaming crisply and see a red mushroom. This red mushroom is a switch. When you press it down, the two birds are not called. When they are released, the two birds sing a beautiful song. This is what I have discovered for a long time.

This reminds me of an ancient poem "Two yellow 鹂 翠 翠 翠, a line of egrets into the sky."
