One paragraph plot summary : While Scrooge McDuck, Donald Duck, Launchpad, Webby and the triplets are adventuring, their plane goes into a bad shape because one of the triplets did something to it. They land on some place called Ithaquack which is supposed to be a myth. The leader takes the reason why his people left is because of Scrooge McDuck. So, he makes a competition against McDuck's family. Meanwhile, Webby and one of the triplets get into the temple and find out more about his mother's disappearance. Outside of the temple, McDuck's family is competing with that leader's son. McDuck's family wins in the end and then, McDuck makes peace with him. On nearly leaving from that place, one of the triplets makes a mistake with that round glass ball that he got from Selene. And then, Launchpad says he finds what's wrong with that plane.
Episode 10 is kind of not interesting. I was kind of looking forward to see more of amazing stuffs. But there wasn't that much in it. That being said, it's kind of funny to see their competition. McDuck's family is so lucky and I like how that leader's son is happy when McDuck's family wins. That's what that shows the friendship. Because of it, I like this episode even though there wasn't any interesting thing going on except for the fact that they got tiny information about the disappearance of triplets' mother.
Overall is that, although I didn't see that much of interesting things, it's turned out kind of enjoyable. I feel like this episode doesn't end. I think there will be continued episode. I think there will be some kind of interesting thing in the next episode. Now, they know more about their mother's disappearance, so, they will try and find their mother. Thus, I guess things are getting interesting soon. I can't wait to see DuckTales' the rest of the episodes.
