I think you mean the Kid Nezha bundle on Roblox mobile. To get it, open the Roblox event game linked to the Nezha/Luobu Mystery Box Hunt, enter the game, and touch the statue or claim point shown in the event area; that’s the step reported to unlock the bundle on mobile as well.

What to do

  1. Open the event game on Roblox.
  2. Go straight to the statue or reward spot.
  3. Interact with it on mobile by tapping it.
  4. Check your avatar inventory after that.

Important note

This kind of event item can be limited-time or event-specific, so if the item no longer appears, it may have already ended or changed.

If it does not show up

  • Make sure you are in the correct event game.
  • Leave and rejoin once if the reward does not appear immediately.
  • Check your avatar “Purchased” or character section for the bundle after claiming it.

TL;DR: On Roblox mobile, join the Nezha event game and tap the statue/claim point to unlock the Kid Nezha bundle.
