Guinea Pig

Guinea Pig is the forty-seventh level of Yeah Jam Fury: U, Me, Everybody!. To access it, the player must clear thirty levels.

A-Side
This level consists of a large boxed area of Steel Blocks with walls separating it into four sections. The walls across the middle consist of Steel Blocks separated one block apart, and there are three Yellow Blocks in the leftmost section and one at the top of the third section from the left. The player starts in the lower left corner of the area, and the mango is located at the top of the rightmost section. To obtain it, the player first must use Fury to break the Yellow Blocks above and then reach the opening on the right wall. The Yellow Block in the third section from the left can also be broken with Fury. They then must ascend through the gaps in the Steel Blocks between the second and third sections from the left using either Yeah to place Yellow Blocks or Jam to boost through them to reach the top of the level. From there, they must fall from the right side and place a Yellow Block with Yeah to enter the opening on the rightmost area, where they can then reach the mango above.

B-Side
The B-Side version of this level shares a very similar layout, except not only is it flipped horizontally, but the "Dunes" gimmick present in Summer Budget is active, in which the bottom boundary of the level slowly shrinks over time. The Yellow Blocks in the rightmost section are replaced with two rows of Ice Blocks, which are also present in the second section from the right, and there are two Fury Flags with Ice Blocks above them outside the right wall. The middle area now has two Yellow Blocks and a Steel Block covering the top, and there are now three Yellow Blocks where the mango previously was. Additionally, there is now a second nearly identical boxed area directly above the original, which has Ice Blocks filling the top of the right half, a wall blocking the middle, and a Yellow Block and Ice Block in the middle gap. The player starts in the lower right corner, and the mango is located at the bottom of the second section from the right in the top half of the level.

To obtain the mango, the player first must use Jam to reach the Yellow Block in the third section from the right and then break it with Fury. They then must place it with Yeah below the two Yellow Blocks in the middle to then break them with Fury. With three Yellow Blocks in their quota, they must fall through the gap in the middle and place them below the main area with Yeah to form a path to boost across with Jam to the opening on the left side. There, they must break the three Yellow Blocks above with Fury and place them with Yeah to reach the opening at the top half of the level. Upon reaching it, they must use Fury to break the Ice Blocks in the way and then break the Yellow Block in the second section from the left. With their remaining Yellow Blocks, they must reach the top of the level and fall off the right side to enter the opening in the wall. They then must use Jam to boost upward and Fury to break the Ice Blocks in the way to reach the mango.
