Found in The Right Side of the Tracks, The Captain of the Gourd wants 5
firecrackers (found in The Outskirts of Cobb's Knob) if you are a Seal
Clubber/Turtle Tamer. If you are a Pastamancer/Sauceror, he will want 5
Razor-Sharp Can Lids (from the Haunted Pantry). And if you are a Disco
Bandit/Accordian Thief, he will want Spider Webs (from The Sleazy Back Alley).
When you bring the 5 items back, you will receive a gourd potion (which
increases your primary substat by around 35). This quest can be repeated.
