- Dee DeeSert and Snack Attack Max
- Game Over Kali and Gamer Greg
- Spikin' Noah and Low Tide Logan
- Racin' Rayne and Lockin'Logan
- Stencil Sallee and Graphic Greg

Box Packaging and Reveals
The packaging has the Series One coloring of purple, with newly styled packaging and a checked pattern, The exclusive Hairdorables character will be visible to the side, dressed with her shoes, and mounted on a small background with plastic shaped for her hair, similar to main series packaging for them.
The packaging on the Dudes side is very much similar to Series Three. It opens with a center-style pull styled like Series One; however, this does not open in the center as it did and instead opens to one side, showing the background on the right with pop-up elements. The Checklist is on top of the perforated cardboard flaps or tucked with the background.
The two stands are translucent, match according to the doll set, and are behind perforated sections One and Two along with a reveal bag, requiring assembly. The item bags are like Series Three, but with a HairDUDEables print. The cover over the Dude doll is a male silhouette similar to where Noah would be.
The packaging for the boy dolls comes in multiple styles of doll packaging, each to accommodate styles; as none of them have exceptionally long hair, they are all enclosed.
- M1, to accommodate the majority of styles.
- M2, to accommodate the mohawk of Gamer Greg
- M3, to accommodate the curled upstyle of Snack Attack Max
