WARNING! This Contains Spoilers!
I assume you mean wormwood, so, after you defeat the Dreadmaster you go back on the starflight express, aquilla betays you and takes all of the fyggs, you fall out of the starflight express and land in wormwood.
There is no Fygg in Wormwood Creek. You're only supposed to go there when you've already gathered all the fyggs.
You have to have beaten swinedimples academy already, swinedimples is around the urdes marshland by batsureg
In the heights of loneliness
There are 7 in the Fygg-gathering part of the main quest. But you may also see a few more later on.
you go to the room with the guy where you got the request in the first place. after that you go to the roof with the guy who is fishing and jump into the center of the water (a "!" will appear over your head). by that time, they will have already have chopped up the fygg, that the lizzard will eat, turn into a giant dragon-like monster thinking he is a human, and take the queen into a well, where you have to go through it and fight him and there will be a cutscene and you will get the fygg.
That depends on where you are. If you're done with the game, and have beaten Corvus, then no. However, during the game, after you find the second Fygg, you can go back there by calling the Starflight Express from the blue trees.
It's post game quest 039, Follow That Fish! You have to talk to Jona Jones and then talk to the ghost of Llevithian's serenader at night. then, go to where you fought Llevithian before, only equipped with a flowing dress, a watermaul wand, and either a silver shield or a silver platter, i forget which. defeat Llevithian, you will get a fygg, eat it, and you will gain control of the starflight.
Realm of the Mighty. If you're post game and haven't regained your ability to use the Starflight Express yet then don't worry; they can be found in higher level grottos too.
Talk to Jona and complete quest 39 "Follow that fish!" by getting a watermaul wand, flowing dress, and silver shield. Then go to the mayors private beach near Porth Llaffan and talk to Jona with the 3 items equipped. Lleviathan will appear and you will go into battle. Once defeated he will give you a fygg and you will be asked if you want to eat it. Press yes and you will see Stella again and take control of the starflight express. (p.s. you have to beat the game to take on this quest)
Zere rocks, cave by Bloomingdale, Stornway (wight night), Coffinwell (soon after defeating (Ragin contagion), Alltrades abbey, (very soon after beating the master of vocations),Porth Llaffan (after beating girls dad that is a freaky fish),Gleeba after beating princesses or queens lizard,and at Swinedimples Academy(after defeating the crazy teacher ghost who ate a fygg)
Alltrades Abbey (1)Porth Llaffan (2)Zere Rocks (3)Bloomingdale (4)Gleeba is where you can find the fifth fygg. of course, there's also Swinedimples and Batsureg, but Gleeba is nearest to Bloomingdale after you get the ship, so i'd say Gleeba
you need to talk to all of the agrivated people, talk to the guy in the back, find Yhe martial artist and talk to him, talk to the guy in the back(again), go to the tower of trades (east), BOW (new party trick) in front of the door, go to the top, find Jack of Alltrades, battle him (Master of Nu'un), get a fig,and go back to Alltades Abby. Now you can change vocation.
You need to download wifi. There is a chain of quests that all lead up to the boss, none other than the sleeping boss, Nodolph, who is pretty much a Nemean clone. Be sure to use Eye for Trouble on him.
About 1500HP And when you complete the game leviathan has around 3000 to 3400 HP and more powerful attacks and you also get a fygg off of the new leviathan to gain access to the starlight express he uses more of the whole party attacks single melee attacks and critical hits now and then to KO your character.
