The contestants have these aplenty. Including those moments where teams gave up well earned gems to get other teammates back even at the expense of their own chances of winning. And then there was that time in The Secret Temple when the entire team jumped on a teammate who was terrified of heights - yet had completed a heights-related challenge and won them the challenge anyway.

Kinsa was just one living Crowning Moment of Heartwarming. A tiny little redhead who went on to win the challenge and never stopped smiling the entire time.
