Autumn Mountain

"Woo-hoo! We're here! Autumn Mountain! The leaves are such a bright shade of red. It's so beautiful!"

- Olivia

Autumn Mountain is a location in Paper Mario: The Origami King, a forest filled with autumn-colored trees and tall, grassy fields. It is the first area of the blue streamer district, first entered via the tram in Overlook Mountain. During the tram ride to Autumn Mountain, Mario and Olivia meet up with a special Bob-omb who is set out on a quest to restore his memories. This is the first area explored in which they travel together. However, Bob-omb ends up being a bit of a nuisance, getting lost quite often and having to get rescued from Chestnut Valley to unlock the Water Vellumental Shrine.

Right after Mario, Olivia, and Bob-omb get off the tram, Olivia comments on its aesthetic beauty as the perfect place to make memories. Behind the tram is a pile of giant coins. As they travel along the way, they reach a dried-up river. Bob-omb becomes excited and runs off. Olivia tries to warn him, only for Bob-omb to come back to correct his name. Despite this, she continues to name him incorrectly, now calling him "Bobby" for the rest of their adventure. When Mario and Olivia follow him down the stream, they reach a few boulders blocking the way. They decide to travel back up the stream only to find a dried-up lake. They find a boat they can use to travel to the blue streamer, but it cannot be used due to the lake being drained.

Mario must travel off to the right, crossing a field of dry, tall, patchy grass where several enemies and Toads can be found. When they get out, it is discovered that Bob-omb became lost somewhere along the way. Olivia decides he must have gotten excited and run off like last time. Moving on, Mario and Olivia finally reach the Water Vellumental Shrine, but if Bob-omb is not with them, it cannot be entered as the door requires two people standing on the tiles to open. Fortunately, Bob-omb can be found on an area just off the dry field, hanging out with a Sombrero Guy. As they try to cross the bridge, a Paper Macho Goomba appears on the other side. Thinking it is friendly, Bob-omb runs toward him and ends up getting knocked off the bridge. Mario must jump off the bridge (which he previously was unable to do as Olivia would warn him not to jump as he may fall off if an attempt to jump is made) and locate Bob-omb several times in Chestnut Valley.

After rescuing Bob-omb, Mario and Olivia can enter the shrine. However, Bob-omb stays outside, not interested in exploring the shrine and finding the Water Vellumental. After the Water Vellumental is defeated and Olivia gains its abilities, they can all return to the dried-up lake and use the Magic Circle to restore water to both the lake and the stream. However, as none of them can use the oar to row the boat, they must first find the oarman, who is actually in disguise as the origami monkey atop a stack of cans. Mario must follow him around and hammer him to rescue the oarman, allowing them to use the boat to reach the Eddy River.
