Is there an Italian version of 'Goldilocks and the Three Bears'?

Apparently not...

In Italy recently, I was teaching a microbiology technique of preparing 3 flasks that would mature at 3 different times so that one would be "just right" when the next step was ready. I tried the Goldilocks analogy on 5 different Italians of varying ages, no recognition whatsoever, nothing even familiar.
