It's nice when you have blankets. You could make things like blanket forts!

[Despite finding a lot of houses back home, Seto and Ren didn't really find a lot of blankets. They either had rotted away or were in uses by people who fell asleep for the last time in their beds. The latter could still be used, but Seto didn't like disturbing bodies. Better to cover them up so they're not cold.

But here they could have blankets if they asked. It's really nice.]

And it's comfy so you can sit down for a long time and be warm too.
