You've got to get all the Kaja'Cola Zero-One that you can and make the goblins drink it to boost their morale and free them!
Progress
Increase their morale, <name>, so that they will run to freedom!
Completion
I hate the Trade Prince, but you can't argue with the results of his methods. Kaja'Cola Zero-One is a huge improvement over regular old Kaja'Cola at half the calories and twice the ideas!
Loot objects as before. Also, Brute Overseers carry them too. In order to find all three of your friends just keep hugging the right wall. It will also get you to the boss near Gobber.
The freed goblins (including your friends) will each yell two "ideas" upon being freed. Some of the ideas include:
"Mom detectors."
"Bagel-holes!"
"So I have this idea for a movie. Three gnomes find a bracelet of power..." (note that this was also a /silly joke for human males)
"We put a whole town... in a tiny little box!"
"How about smiling monkey wallets?"
"Explosive fire extinguishers! We'll fight fire... WITH fire!"
"Spoon sharpeners!"
"A truck that delivers ice cream. With a catapult."
"I've got it: Squeezeable rocks!"
"Clowns. Instead of making you laugh, they're there for beating."
"Thirteen-sided dice!"
"Tauren paladins!" (a reference to the fact that before Cataclysm there were no tauren paladins, along with a few other race-class combinations)
"Invisible condiments. For an unobstructed view of your food."
"Feed pigs rubber, 'till they bounce. There's got to be an application for that."
"A globe that shows the inside of the planet... on the outside. So you know where to dig!"
"Handheld one-way mirrors!"
"Nose-stenders. For smelling things in different rooms."
"Attach two vehicles to a bigger vehicle, and then have the passengers jump from one vehicle to the other!"
"Electrical wires used to send messages over great distances... no, impractical. Giant rockets, with speakers attached..."
"Houses made of dirt! When you clean them... THEY'RE GONE."
"Stairways... for horizontal surfaces!"
"Half man... half sharkalligator!"
"Leashes... with pre-attached pets."
"A big convention, see? To show off all of our inventions. We'll call it GoblinCon. And we'll give away special pets! Except most people will probably sell them for profit on the auction house."
"Distilling the juice out of Kaja'mite to make a delicious, carbonated beverage that will give people IDEAS! Hey, wait a minute..."
"Giant gnomes! No, wait... tiny giants!"
"Goblins with gills!" (a reference to the goblin mobs in Vash'jir)
