The Pink Whale Challenge (known as Baleia Rosa) originated in Brazil in 2017 as a wholesome counter-movement to the harmful Blue Whale Challenge. Created by graphic designers and publicists, the initiative aimed to prove that the internet could be used to spread viral positivity and hope rather than self-harm. Instead of dangerous dares, participants are encouraged to complete daily acts of self-care and kindness, such as writing down things they love about themselves or forgiving someone. The meme became a global symbol for mental health advocacy, often used to combat online toxicity and encourage emotional well-being through simple, uplifting challenges.
