Rapunzel's Tangled Adventure, Season 3

Varian:
Oh! Okay, there's the base. Encasing it in amber should stop the fear-- (jumps off the stairs and runs to the base of the device when he points to it) (rumbling) (Varian yelping)

Rapunzel:
Okay, less explaining, more pouring. (pushes Varian) (unties her hair to put around Varian's waist when he walks to the red rock but he is scared) (rumbling)

Quirin:
Varian! Please help me! (Varian hears and sees his dad calling him) (Varian is scared and he sadly sees his solution but pours his solution on a red rock then runs back to Rapunzel) (Rapunzel shields her and Varian) (Pascal squeak) (rumbling continues) (Rapunzel stops protecting her and Varian)

Varian:
What? Gah, I don't understand! This solution should encase the red rock... Oh, of course! Oh, so dumb, Varian! Whatever turned these rocks red must've also changed their internal chemistry.

Rapunzel:
So, that solution only works on black rocks?

Varian:
Yes. Well, what's left of it. (tapping his beaker) But, I... I don't even see any black rocks. (tries to find black rocks)

Rapunzel:
I do. (puts one of her hand on Varian's shoulder when she points to a black rock at the top) (Varian walks closer to the edge to see a black rock) (suspense music playing)

Varian:
Okay, this just got a lot harder.
