Mount Asia is where Tricia Takanawa found the inspiration for her bestselling book Throw It Away, in which the readers are taught to declutter their lives by getting rid of things that no longer bring them joy in "Throw It Away".
Lois takes this advice to an unhealthy extreme, driving out Peter and the kids. When this fails to bring her the joy she desires, she goes to Mount Asia to find out why. Peter in the family follow, where they find her on a rope bridge, high over a river. But when Peter tries to cross to her, his movements on the bridge cause her to fall over and plummet towards the river. She is saved when she falls into a passing garbage barge and realizing that every little thing in the house brings her joy, decides to keep it all.
