The torso

Cause that's where the heart is

And they love eachother

They might vacation to the extended arm, imagine climbing all the way to the top and standing in the palm of the hand of the Titan to see out into space

It's like the Mount Everest hike

I'd say the torso because, one, it's the largest section and so would have the most of everything, and two, because it gives them access to all other areas of the Boiling Isles.

SCREW THAT, IM TAKING THE CORPSE

D4C LOVE TRAIN!
