Venancio was an old inventor who lived alone in a small house on the outskirts of the city. He had so many rare objects all around the house. One day he got a violin as a gift; so he started to play it; after sometime he liked it really much, so he stopped using his tools: CASIMIRO The wind up mouse and CLEMENTE the robot. Because of that, Venancios tools got jealous of the violin and they decided to destroy it. However, at the end they repaired the violin to restore their happy relationship that they used to have with his friend Venancio.
