Tunes on the Dunes
Tunes on the Dunes is a level released by William Abeel on November 30, 2017. It is the first custom stage to be released by a developer of the game.

The level consists of two large groups of Steel Blocks in the shape of minim musical notes with tails facing each other and Yellow Blocks filling the note heads and the gap between the tails. The player starts on the left "note head" and the mango is located on the right "note head". To obtain it, the player must use Jam to boost up to the Yellow Blocks above and then switch to Fury to break through them. The player may then either advance to the top of the "tails" or use Yeah to place Yellow Blocks underneath the Steel Blocks to reach the mango on the right.

Birdfeeder
Birdfeeder is a level released by William Abeel on December 2, 2017. It is a remake of the level of the same name from the original Yeah Jam Fury and shares an almost identical design.

The level consists of a small platform of Steel Blocks with a massive wall to the left and three Yellow Blocks below. The player starts on the platform, and the mango resides on the left side of the wall. To obtain it, the player must break the Yellow Blocks with Fury and then use Yeah to place the Yellow Blocks to either traverse underneath the wall or boost over the top of it with Jam.

This is My Horse Stage!
This is My Horse Stage! is a level released by William Abeel on December 8, 2017. It was used in the Stage Builder video released by World Entertainment Studios to demonstrate the process of creating a custom stage.

The level consists of a large group of Yellow Blocks, Steel Blocks, and Ice Blocks in the shape of a horse facing left, with Steel Block representing its main body, Yellow Blocks representing its eyes and hooves, and Ice Blocks representing its mane, tail, mouth, and nostrils. The player starts with one Yellow Block in their quota on the "tail" of Ice Blocks, and the mango is located within the "backside" of the horse. To obtain it, the player must place the Yellow Block with Yeah to reach the "hooves" of Yellow Blocks, which can then be broken by Fury. The player can then reach the "mouth" of Ice Blocks and break through with Fury to enter the group of Steel Blocks and then advance right to reach the mango.

Ditch The Ice!
Ditch The Ice! is a level released by Gregory McLeod on December 12, 2017. The level consists of a small rectangular box of Ice Blocks with a platform of Steel Blocks at the top. The player starts on this platform, and the mango is located on the platform of Ice Blocks below. To obtain it, the player must fall through the Ice Blocks as Fury and fall toward the mango.

Windowsill
Windowsill is a level released by William Abeel on December 15, 2017. It is a remake of the level of the same name from the original Yeah Jam Fury and shares an almost identical design.

The level consists of a small platform with a wall of Steel Blocks to the right and a platform higher up, representing a windowsill. Unlike in the original level, there is also a group of Steel Blocks above this to represent the head of a window frame, and rather than there being a Yellow Block to the left, the player starts with one in their quota. The mango is located on the "windowsill", and to reach it, the player must first use Yeah to place the Yellow Block and use Jam to boost to the Yellow Block and then to the platform.

Unfair FunFaire
Unfair FunFaire is a level released by William Abeel on December 24, 2017. The level consists of a small platform of Steel Blocks and a group of six Steel Blocks forming a wall with a platform at the top, and there is a Yellow Block between them. The player starts on the left platform, and the mango is located directly below the right platform. However, it is locked and can only be obtained with one Yellow Block in the player's quota.

The player must first break the Yellow Block with Fury and then use Jam to boost to the Steel Blocks to the right. They then must place the Yellow Block close to the mango so that they are able to stand beside it. To obtain the mango, they then must fall through the Yellow Block with Fury while making contact with it.

Jam Takes A Vacation
Jam Takes A Vacation is a level released by William Abeel on December 25, 2017. It was used in the quicktricks video for "The Smash Mouth" released by World Entertainment Studios to demonstrate the technique.

The level consists of a large boxed area of Steel Blocks forming a narrow path to the right and then upward, with several sets of Yellow Blocks blocking the way. A Yeah-Only Flag is located in the middle of the path. The player starts on the left side of the path and the mango is located at the upper-right corner. To obtain it, the player must first use Fury to break through the two leftmost sets of Yellow Blocks and then switch to Yeah or Jam to go through the shorter path. Upon reaching the Yeah-Only Flag, the player must use "The Smash Mouth" to break through the following Yellow Blocks by placing a Yellow Block at Yeah's head or using the Quick Block directly below a ceiling. Alternatively, the player may avoid using the path altogether by placing a Yellow Block near the start of the level and then using Jam to run up to the top of it.

Levels
Levels is a level released by William Abeel on January 3, 2018. It was used in the quicktricks video for "The Wallflower" released by World Entertainment Studios to demonstrate the technique.

The level consists of seven walls of blocks, each of which has a repeating pattern starting at the top of two Steel Blocks, then two Ice Blocks, and finally two Yellow Blocks. From left to right, these walls ascend in height, though the rightmost wall is the shortest. The player starts at a Jam-Only Flag on the leftmost wall, and the mango is located on the rightmost wall. To obtain it, the player must use Jam to ascend each wall through boosting and wall running. The first two walls can be cleared simply by jumping and climbing over, though the next three walls require the player to use "The Wallflower" by boosting upward and wall running for as long as possible before jumping to the tops. Upon clearing the highest wall, the player is then able to drop down to the right to reach the mango.

The Bars
The Bars is a level released by William Abeel on January 9, 2018. It was used in the quicktricks video for "The Bee Sting" released by World Entertainment Studios to demonstrate the technique.

The level consists of a large boxed area of Steel Blocks with five groups of Steel Blocks forming barriers, each with a pattern with sets of three Steel Blocks arranged diagonally. Each barrier is split in one area by an additional block of height, forming gaps, with the leftmost gap being filled by a Yellow Block. The player starts on a Steel Block in the lower left corner, and the mango is located in the upper right corner. To reach it, the player must first break the Yellow Block with Fury and then use "The Bee Sting" by using the Quick Block while directly underneath the ceiling to the left of each gap. This switches to Fury and allows the player to traverse to the other side each gap. For the rightmost gap, the player must first boost up to it with Jam before using the Quick Block to reach the mango on the right.

5 Year Mangoversary!
5 Year Mangoversary! is a level released by Gregory McLeod on December 15, 2022. It was created to celebrate the game's fifth anniversary.

The level consists of twenty-six Yellow Blocks in the shape of the number 5 with thirty coins surrounding it in ten groups of three each. The player starts on the right side of the top platform, and the mango is located above the bottom platform. However, it is locked and can only be obtained with $3.00 acquired, which includes every coin in the level. To obtain it, the player must first collect each coin, with certain coins requiring the player to place Yellow Blocks with Yeah after breaking some with Fury to reach them.
