Question about some quests.

[Sroths]

there are 4 more quest for ep1&2 plus:
Ep:2
-seat of heart:here you mus win a competition on temple, spacechi, and then beat gol dragon. Then in the second part you mus help elly to find cal and talk to him in the control central area, then you enter to the control tower (new for ep 1&2 offline). there you will find new enmies as ill gill, del lily, mericarol, mericus, meri(i dont remember), gi-gue, and the big monkey(dont remember the name)there when you finish the 5 floors you will talk and then finish the quest.
-The east Tower:there you pass central control area and the control tower east(lol)
you pass the 7 floors and fight epsylon(like a mini vol-opt) and then finish the quest
-The west tower: is the same as the east tower but in the west(lol again) and with 9 floors and 2 epsylons
(i dont remember in which but at the end of one of tose quests you will appear in tener sinus, the beach of gal da cal and there willl appear credits, ahh, i remember, it was seat of heart and there you talk again with elly)
Ep:1
-central dome fire(or something like that):here you must turn off a fire made by the Hildebears foie(you will hear a new bgm)

I have a question:
