The American Red Cross has partnered with the popular cartoon brand Peanuts to create an exclusive T-shirt featuring Snoopy for people who donate blood. Now, the shirt is going viral on TikTok and first-time blood donors are showing up to get their hands on the exclusive merchandise.

The collaboration has increased traffic and the number of appointments for blood donations, according to the Red Cross. He has found an audience on TikTok, with users documenting his visit and his new T-shirt, which features Snoopy’s alter ego Joe Cool and the phrase “Be Cool. Donate blood.»

Cathy Chang, who goes by @uh…o_o on TikTok, posted a 6-second video Wednesday of her shirt that garnered more than 4 million views.

He said that he saw a video about the collaboration, which runs from April 1 to 23, from another user and decided to donate blood for the first time because of the T-shirt.

“If I see something nice and I don’t have to pay for it, I’ll do whatever it takes to get it,” he said.

Commenters on her video shared their feelings about the hype around the collaboration.

“They are finally realizing that we will do anything for the merchandise,” one person commented.

“I literally skipped class to go donate blood to get my shirt,” another person wrote.

Chang, 24, said she had wanted to donate blood in the past but was afraid she might faint. This shirt, however, was enough to face that fear.

Darren Irby, executive director of national brand partnerships for the Red Cross, said it’s been exciting to see the momentum of this collaboration.

“It’s been really great to see so many young people so motivated by this particular partnership and realize that maybe their fear of needles or other concerns aren’t as bad as they thought they might be,” he said.

Irby said some of that success could already be seen in his data.

“We’ve seen web traffic to our dating site – as of Monday, it’s up 50% compared to our six-month moving averages,” he explained. «What’s really cool and speaks to the social aspect of this is organic search is up 600% in the last few days.»

The Red Cross has done similar projects for «Game of Thrones» and «Wonder Woman 1984,» but Irby says Peanuts fans are more multigenerational than fans of other brands, which probably helped with the scope of the collaboration.

“Several years ago, we made a conscious decision to inspire new donors through the lens of their existing interests and their own passion points,” he said. “We do this a few times a year, and it really made a difference. So we strategically approached Peanuts because we loved the cross-generational appeal it [it] Offered.»

Irby said young people are often introduced to blood drives through their high schools, but the pandemic has made the drives less and less accessible. Social media has helped bridge some of that gap.

Chang said she is thankful her video went viral and helped spread the word about the new promotion.

“I’m glad this TikTok has gotten a lot of attention because a lot of times, no one will go out of their way to look for where they can donate blood, but then they see this incentive on social media,” he said.
