Chapter Four: Alpine Peaks (Free Roam)
The Lava Cake peak is the large cake-like volcano that is oozing lava off in the distance from the main peak in Free Roam. The only trick to this is either using the Time Stop Hat (acquired from yarn found in this chapter, requires 24 yarn to knit) and use it to slow down the rising/falling pillars or to take breaks between them. You will need to use the Dweller's Mask to reveal certain platforms. It would be safer to take an avoidance approach to any enemies or obstacles that aren't lava, just in case it leads to interacting with the obstacle in question.
