Hidden Sound 6
On Via della Constituzione, across from number 15/1, along the Crostolo, you can find the object to reproduce this sound.
You can find the same object in two materials, but you have to use the right one to make the right sound come!

It’s a “tum pa” sound ! But you have to do it on the metal one! On the plastic one it doesn't come out right! We recommend the third one, it's the one that sounds best! Find it!
