Hands off the strongbox while the little winged cube is in. It's decided the strongbox is family, so it stands guard beside it with that spiked mace up. The cellar boy tried for the strongbox and went home with a star-shaped lump. Nobody's had the nerve to tell it boxes don't have parents.
DM tip
Give it one rule it follows to the letter and let the party find the loophole. A construct that obeys exactly makes a better puzzle than a fight.
