This quest takes place in Vault 317, which has a random layout with around five floors. Enemies include mole rats and radroaches, with the possibility of glowing radroaches. The objective is located around the bottom of the vault, in which the dwellers will remark about only finding four-leafed clovers. The room the objective is in contains two Nuka-Cola Quantum and a rare outfit recipe.
- "Well, that's disappointing."

- "...but all the samples here have four leaves. Must be a different plant."
- "What rotten luck. Come on, let's go home."
- "Top o' the mornin' to ya!"
- "Erin go bragh"
