At this time, Mary wandered into the bog. Her legs and shorts have become dirty and wet.

Mary walked through the mud, and then sank into the quicksand. Mud slurry reached her breasts.

The scene consists of 3 parts:

"Dirty shorts"--the first entry in the swamp, Mary immersed to the waist, and her clothes in the mud smear.

"Not too deep"--she managed to escape and now she is walking, his feet sinking into the mud.

"Almost sunk!"--oh, oops... Mary stuck deep, but she likes it!
