Surf's Up 2: WaveMania: Quicksand Scene
Movie
This scene when The Undertaken was stuck in quicksand and Cody, Lani, and Paige tried to pull him out, but he's too heavy like a boulder, but luckily J.C. manage to pull him out when he was strong enough. It was seen again when Cody was knocked down and almost fully sank in until J.C. grabbed his hand and got him out.
I can admit the movie is bad, but I like the scenes though.
