I don't really know. I think it would be the very first one or the cavern one.

I like the first one because it was really simple and Fabian and Nina knew what to do. I loved how it had a reference with Robert Frobisher-Smythe.

I also liked the one where they used the crocodile as a bridge. I liked our because of many reasons:

They got Sibuna back together.

In the episode where Nina finds out how to solve the challenge, Peddie dances. (They are my favorite episodes; Season 2 Episode 23-25.)

Fabian saves Nina from falling down the cavern.

Yeah, definitely my favorite episodes.

Sibuna! •Leah♡♡

I think I'd say the crocodile bridge too.

Because:

1. They got Sibuna back together

2. I love when they're practicing (for both getting it down and getting across)

3. I love when Patricia says "Okay, whoever doesn't have a swinging pendulum in front of their face, SHUT UP!"

And yeah, I just love that challenge.

So ya.

The crocodile chasm.

Sibuna!
