Heartwarming / Endless Ocean

  • Blue World contains little cutscenes that can be viewed by swimming into the right area during the right conditions (time of day, weather, etc.). Among them are scenes of a mother caiman caring for its young, manta rays partaking in a courtship dance, monk seals laying around acting all cute, and green turtles laying their eggs and their subsequent hatching.
  • The scene where Jean-Eric reads his son's letter.
  • The end of the guitar-based sidequest.
