Walkthrough notes

Step 1: Jake, who works at the subway entrance, is scared of Stirges. Go ask Mong from Kong in Kerning City.
Step 2: Mong from Kong wants 10 Bubbling's Huge Bubbles and 10 Stirge Wings. Both mobs are in the Kerning City subway.
Step 3: he still needs a final ingredient, a Vitamin Gummy from his grandfather, Mr. Goldstein in Lith Harbor.
Step 4: bring the Vitamin Gummy back to Mong from Kong.
Step 5: deliver the Special Stirge Phobia Cure to Jake.

Where to find the monsters

Spawn counts from the game data, densest first:

Bubbling (Lv. 15, 259 HP): Line 1 <Area 1> (64, Bubblings only), B1 <Subway Depot> (9)
Stirge (Lv. 20, 296 HP): Transfer Area (38, Stirges only), Dangerous Steam (38), Dark Cave (35). Skip Line 1 <Area 2> (21) and Line 1 <Area 3> (18): they're packed with Lv. 34 Jr. Wraiths, and Area 3 also has Lv. 48 Wraiths, far too strong at 17.

Drop rates for the bubbles and wings aren't in the game data.

Total rewards

Reward	Across the whole chain

Step 5 item	one at random: Pet Equip Speed Scroll: Intermediate (25%), Pet Equip Speed Scroll: Greater (25%), Pet Equip Jump Scroll: Intermediate (25%), Pet Equip Jump Scroll: Greater (25%)

Is it worth it?

Yes, for Kerning City citizens. It's the Kerning City counterpart to Henesys's A Family Reunited, with the same 300 Kerning City Contribution and the same random pet scroll at the end. The only farming is 20 drops from two subway mobs, and the trip to Lith Harbor is the longest walk. EXP and mesos: 687 EXP and 388 mesos on step 1, then 982 EXP and 555 mesos on each step after (4,615 EXP and 2,608 mesos total, about 42% of a level at 17 against 11,040 to level), plus 10 Blue Potions.
