Finding frog tiles

In Vercelli, me and my dad went looking for frogs. The frog tiles mark special places. There are 20 special places where frogs are supposed to be. When we got to the first place we looked on the side walk and found the frog. The second place we looked on the sidewalk a while and then we went to the other side of the road and found the frog. The third frog was right in front of the museum that it was marking. We got so excited and then we went to the fourth frog and couldn't find it. We went to the fifth no frog. Sixth no frog. And then we started to think they didn't put any more frogs. We went to all the ones we wanted to and then went where Momma was and looked for the frog there. And we couldn't find it.
