Yoob's Belly

"I surmise we're inside that beast's gastric chambers..."

- Stuffwell

Yoob's Belly is a sub-location of Yoshi's Island in Mario & Luigi: Partners in Time. It is accessed after the Mario Bros. beat Kamek, where a Yoob enlarged by Shroob saucers eats the Mario Bros. and Baby Bowser. The boss of the area is Sunnycide. Yoob's Belly is a bio-engineered factory inside of itself, which traps Yoshis in eggs. This transforms them into Yoobs if they are not freed in time.

Layout
The first section of Yoob's Belly consists of a main room branching off into five other rooms. The main room also has protrusions that the babies brothers can be thrown into. One of these protrusions contains a fruit which must be given to the yellow Yoshi. The left-most room contains a red Yoshi trapped by an RC Shroober which must be fought. The second room from the left contains two spots that change colors when hit by a hammer. When those spots match the colored spheres on the wall, an opening appears. The baby brothers must use Baby Drill to pass underneath. The following room has sixteen of the colored spots which must be matched with the spheres in the other room to free the blue Yoshi. The middle room contains a Save Album and many enemies. The fourth room from the left contains many spikes and a trampoline that the baby brothers can use. Taking the trampoline takes them to a room with five holes. The baby brothers must drop down the middle hole to reach the pink Yoshi. Hammering the spot nearby forms platforms above the spikes, freeing the pink Yoshi. The right-most room contains a cyan Yoshi being attacked by an RC Shroober. Baby Drill must be used to reach an adjacent room that contains a pump. Baby Mario must use Baby Pump to hit the RC Shroober's Shroob saucer. Doing so blows up half the wall, allowing the brothers to fight the RC Shroober. Saving these Yoshis allows them to push the Chomp Rock, opening the path ahead. Going down the newly formed path leads to a Warp Pipe.

Taking the Warp Pipe takes the brothers to the second section of Yoob's Belly. The first room contains many enemies. The second room contains two eggs containing Yoshis which must be smashed open by hitting the blocks they are in and pushing them into a wall with Baby Pump. Doing so allows the Yoshis to push the Chomp Rock blocking the way. The third room contains more enemies and branches into two rooms. The bottom room contains Yoshis that give the brothers items if they are spoken to and a 4-Bros. Random Block. The top room must be opened by pressing a 4-Person Panel. In this room, Toadbert explains he lost his memory and gives the brothers his drawing. The penultimate room contains another Save Album. The final room contains Sunnyside and beating it opens the exit.

The group can go back into Yoob's Belly anytime in the game by going up the mountaintop, though once they get inside, they will have to exit through the passage in order to get back on Yoshi's Island.

Trivia

 * If the Baby Mario Bros. dig underground while in Yoob's Belly and when his belly is expanded, the player can see the Yoob suffering in pain on the Top Screen. This no longer happens after Sunnycide is defeated, however.
 * While the Mario Bros. are inside Yoob's Belly, Yoob can be seen scratching his lower jaw on the top screen, when the creature is actually holding on one side of the mountain. This no longer happens after Sunnycide is defeated, however.
 * In the North American version, the Save Album is located in the main room of the first area of Yoob's Belly. In other versions, the Save Album is located in the north.
