Heartwarming / Peep and the Big Wide World

• The entire premise of the episode "Quack Hatches an Egg". The first thing Quack does when he sees a baby bird hatch out of its egg is to shed Tears of Joy. His reaction to the baby bird is so sweet, it's hard not to smile. Furthermore, he is so awestruck by the experience, that he decides he wants to raise a baby of his own.
  • Quack to the baby bird:
  Quack: I'll be your Quack, your very first duck.
• In "Quack's Stuck Stick", Quack and Chirp find a pretty stick^note Actually a pinwheel. Instead of bickering over who gets to keep it, or disagreeing about what it is, they decide to play with it, together, and what follows is a montage of the two innocently playing with it, for fun, not competition, and just in general getting along. What makes it even sweeter is that Peep, who usually has to be the mediator and prompt Quack to be nice, isn't present. And then even after Beaver Boy accidentally takes the stick, they are upset, but not with each other, find Peep, and work together to find it.
