- The Stinger at the end of the credits has a cute little bonus: a carving Samus made as a little girl during her time growing up with the Chozo. The carving can be seen during the fight against the Chozo Mural, but the player has to squint at the bottom of the screen to see it and no details about it are evident until the game's ending. Awwww!
- A previous cutscene give us a glimpse of Samus's childhood.
