Heartwarming / Don't Starve

  • Many players grow particularly fond of Chester, the mobile chest. The Klei team seem pretty fond of him as well because they keep coming out with stuff like the above link.
  • Lucy the Axe can be creepy sometimes, but she genuinely cares for Woodie's wellbeing and warns him when he's getting too enthusiastic in his wood chopping - even though she herself loves the activity as much as he does.
  • You have the choice to set Maxwell free if you complete all five realms of adventure mode. Granted this does lead to you unknowingly trapping yourself in his place but the gesture is nice, all the same, especially given how much he tormented you.
    Maxwell: I guess I deserved that.
  • Some of the lines characters give when discovering skeletons in the wild are oddly sweet. Woodie apologizes to them, while Willow hopes aloud that whomever they were, they got to go out in a blaze of glory.
    • With Willow's love of fire, of course, it's very possible that she hopes that they literally went out in a blaze of glory. It makes the sweetness a bit more odd, to say the least.
  • In order to unlock the character Webber, you have to give his skull a proper burial.
  • Wilson, Willow, and Webber celebrate Winter's Feast (the Don't Starve equivalent to Christmas or Hanukkah) together in Starver's Carol. This is even nicer when you consider that Wilson and Willow are both (to some degree) aracnophobes, and Webber is basically a giant spider (of course, it helps that he's also half boy).
    • Also, Maxwell's reaction to a glass of Heavenly Eggnog from the same event, which ostensibly references Charlie, who is currently occupying the Nightmare Throne, half shadow monster, and indirectly trying to kill the survivors:
      Maxwell:: My... favorite... she remembered.
  • Klei released a comic Where Wes gives everyone some Valentine's Cheer.
  • In the Ruins, there's a boss called the Ancient Guardian. If you kill it while playing as Maxwell, his examination quotes for its dropped horn and loot chest reveal that they were once old friends and that he feels remorseful about killing it. This coming from someone who usually acts like a jerk to most things.
    • Fridge Brilliance/Heartwarming: The Ancient Guardian's character design and attack pattern (quickly charging at the player with resting intervals where it doesn't move) are quite similar to that of the Clockwork Rook's. The Clockwork Chess Monsters are Maxwell's creations. Perhaps he modeled them after his old friend. Even though now they both try to kill him.
