Catacombs

Catacombs is the seventeenth level of Yeah Jam Fury: U, Me, Everybody!. It is one of the twenty levels available at the start of the game.

A-Side
This level consists of a large rectangular box of Steel Blocks with eight vertical walls spaced one block apart, of which the six in the center each have a set of three Yellow Blocks in a certain location. The player starts on top of the upper left corner of the box where an opening is, and the mango is located between the two rightmost walls. To obtain it, the player must fall through the opening and use Fury to break through the Yellow Blocks in each wall, while also using Yeah or Jam to reach each set of Yellow Blocks. Doing this, the player must go through the openings formed in each wall to reach the mango.

B-Side
The B-Side version of this level shares a very similar layout, except not only is it flipped horizontally, but some of the block layout has changed. Particularly, the two rightmost walls have additional Steel Blocks on top and the two bottom rows of Steel Blocks have been removed, making it possible to fall within the boxed area. The player now starts at a Jam-Only Flag, and the opening is now covered with an All Flag. Additionally, Yeah is excluded from the level, so the player is unable to switch to him at any time. The player also can no longer refoot, and instead the level will restart if they fall.

To obtain the mango, the player now must reach the leftmost wall without falling. Notably, the first, fourth, and sixth walls that must be crossed have Yellow Blocks at the bottom, which has no Steel Blocks to catch the player with. To break these without falling, the player must switch to Fury while still partially surrounded with Steel Blocks, which can be used to break up to two Yellow Blocks to use the third as ground to stand on. Alternatively, the player can do this to break all three Yellow Blocks and then switch to Jam before falling.
