El caso del papagayo

Hot chocolate, the sofa, and a cozy blanket! That was my plan for the coldest afternoon of winter... until my cousin Trap showed up with an injured and very noisy parrot. We named him Echo, and—between pecks—he kept repeating a bizarre phrase: "Dig, you dummy! The gold is under the river!" Just the ramblings of a crazy parrot... or a secret clue to hidden treasure? To find out, you’ll have to join me on an investigation full of mysterious tunnels, homemade traps, and super-mousey laughs. Help me decipher the bird's squawks and unmask the digging gang before they leave me without ears or whiskers!
