Heartwarming / Yoshi's Story

• At the end of every level recap, the narration tells you that "The page turned, and the Yoshis grew happier", along with a retelling of all the fun (mis)adventures they had to get to that point.
• The ending credits, with appropriate music and a recap of the Yoshis' brave adventures, ending with all of them (including the white and black Yoshis if you found their eggs) gleefully jumping around the newly-returned Super Happy Tree, celebrating their victory. Finally, the book closes, and "HAPPY END" can be seen on the back.
  All's well that ends well. The Yoshis had broken Bowser's spell.
  The Super Happy Tree was back. They jumped for joy with their fruity snack.
  And the Yoshis lived happily ever after.
• If you stand still at high (or maximum) health, the Yoshi you are playing as will march in place and sing a little tune. It's absolutely precious to watch, as are a lot of their Idle Animations in general.
