Talk to the slime that you are teleported to and choose to get gooed up for a Level Restriction of 1.
You can now "capture" blue Slimes by defeating them, so capture 100 slimes to obtain 100 slime coins.
The Slimes occasionally flee, instantly ending the battle and granting no slime coin.
Chance of fleeing increases when the slime takes a large amount of damage quickly, but is left with a small amount of health (i.e., a high-damage attack leaves the slime near death, but does not finish it off).
Stone is the most effective attack against it, and it is available to any job using /BLM in this event, assuming the spell has been learned.
Return to the slime who "gooed" you up, and choose to return to the starting slime in the city.
