Astro 1-up is a hard difficulty stamp in Club Penguin Rewritten. It can be obtained by collecting 8 1-ups in one playthrough of Astro Barrier.


  • The 1-up at the tutorial screen before Level 7 counts towards the stamp.
  • Restarting a level does not reset the 1-up count, meaning that the player can get all 8 1-ups in one level by purposefully restarting it.
