Midnight Snack
Midnight Snack starts with Lo Wang finally delivering the raccoon near the dragon's position. However, things don't go according to plan, and while the beast did swallow the animal, the mask went off too quickly and didn't kill the dragon. So now Lo Wang has to take things into his own hands and finish the job himself.
Finishing this part of the game will unlock the achievement/trophy "Inside Out."
Chasing the Dragon
Once the cutscene is over, move forward, following the path.
This part of the game is pretty straightforward; just keep moving forward, follow the path and try not to die by the falling icicles or by falling off the track.
After using the grappling hook to shatter an ice wall, you'll slide down a surface, and then you will need to use the grappling hook again to get closer to the dragon.
A cut scene will start marking the end of this game section.
