The rock oil and the medallion

In one beautiful sunny day, Alberto decided to keep collecting human parts. After all he didn't have anything else to do. He accidentally found a medallion with two golden fish with blue rock for eyes.

- Luca, come on, where are you going?! - Alberto yelled panicked
- I must find the thing you gave me! - his boyfriend replied.
