I believe that's S1 E2

I'm watching S1E2 right now and I don't think it's getting anywhere near the clip...

...

...maybe Kilmarnock should know. @Kilmarnock228

It is indeed from episode 2. Should be the scene where Scrooge and Dewey are traversing the rope bridge.

Well, I know for sure it isn't in Season 1, because I just watched the episode...I'll try seasons 2 3 and 4.

@Talking4flowers the DuckTales reboot series only had three seasons…

Ah, I understand now. I don't know why I was thinking 4 seasons...
