KATSEYE has partnered with Hershey's, reimagining their iconic "Pinky Up" gesture for the Hershey's Crème Bar campaign. The collaboration represents a full-circle moment for the group, connecting their current work with childhood memories of enjoying Hershey's products and demonstrating how their recognisable trademark has evolved beyond their performances into commercial campaigns.

The group members have each been assigned chocolate alter egos matching their personalities—Daniela as dark chocolate with almonds, Lara as salted caramel, Sophia as strawberry crème, Megan as cookies and crème, and Yoonchae as matcha white chocolate. The partnership accompanies KATSEYE's Wildworld Tour, which the group views as a significant milestone in their evolution since their debut, during which they emphasise the importance of supporting one another through recent group changes, including a hiatus for members Sophia Laforteza and Manon Bannerman.
