Locked Box

Locked Box is the fifty-first level of Yeah Jam Fury: U, Me, Everybody!. To access it, the player must clear thirty levels.

A-Side
This level consists of a boxed area of Steel Blocks containing the mango with an opening on top covered by Yellow Blocks. Above this area is a group of ten Yellow Blocks, five of which are spaced in a row at the top with the other five placed in a trail leading from the rightmost block to the opening of the boxed area. The player starts at a Yeah Flag on a Steel Block to the left of these Yellow Blocks, and there is a Fury Flag on a Steel Block to the right of them. To obtain the mango, the player must jump across these Yellow Blocks to reach and pass the Fury Flag. As Fury, the player then must drop down to the left and fall through the Yellow Blocks below. They then must clear the opening of the boxed area and fall through 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 there is now a coin above each of the ten Yellow Blocks above the boxed area, and the mango is now locked and can only be obtained with $1.00 acquired. Additionally, the opening is now only two blocks wide and is filled rather than covered with Yellow Blocks, and many of the Steel Blocks on the bottom are replaced with Yellow Blocks. The player also can no longer refoot, and instead the level will restart if they fall. The player now must collect all ten coins, break both Yellow Blocks in the opening when falling, and avoid falling through the Yellow Blocks at the bottom.
