Pair 153:
1. Added a faint, horizontal, white line in the ice wall a bit above Jynx's lips. Forms a triangle like this: /_\ (with the bottom line being new.)
2. Took off the lips of the left-side Jynx
Somehow found the wall mark first. Cannot really see that left-side Jynx clearly, though, so perhaps not that surprising.
Marked up the image for pair 154. Seemed easier than trying to describe the tree difference.
