A player shared an Easter egg for "Hello, Luigi!" on the Switch 2 home menu: launching the app with a specific button combination changes the Luigi-themed icon to Waluigi and displays corresponding text. This change is limited to the console interface and does not alter the app's content.
The operation shared by players involves selecting "Hello, Luigi!" on the home menu, holding down the specified left shoulder button on the controller, and pressing the A button to launch the app. The Easter egg does not make Waluigi appear within the app, nor does it add levels or gameplay mechanics.
"Hello, Luigi!" is a small app designed around touch-screen interactions. Players can touch and pull Luigi's face to see different expressions, or play simple mini-games like hide-and-seek. The discovery this time relates to a visual change in the menu icon.
