Pediatric Brain Tumor Foundation: Imaginary Friend Society
The Pediatric Brain Tumor Foundation tasked RPA with expanding their mission. They needed to help children and families navigate the terrifying experience of a cancer diagnosis. The goal was to create resources that reduced anxiety by explaining complex medical procedures and terminology in a way that was accessible, engaging, and comforting for young patients during their long and grueling treatment journeys.
Creative Idea
Created a society of animated imaginary friends to explain scary medical procedures to children.
The campaign simplified the terrifying experience of pediatric cancer by creating a series of animated films where whimsical imaginary friends translated complex medical procedures into relatable kid-speak, empowering children with the understanding needed to face treatment with less fear.
Twenty Two Studios and One Giant Camera
The Pro Bono Powerhouse
To bring the Imaginary Friend Society to life, RPA orchestrated a massive collaborative effort involving 22 world-class animation studios who all worked pro bono. While RPA provided the scripts, they granted each studio total creative freedom over visual styles. This resulted in a diverse aesthetic "society" where characters like Sully (the hair loss expert) and Hank (the hermit crab explaining hospital stays) look entirely different but inhabit the same universe. Notable contributors included The Mill, Psyop, Titmouse, and Gentleman Scholar.
Translating Oncology into Kid Speak
The campaign filled a critical medical gap by replacing clinical jargon with relatable metaphors. Instead of "Magnetic Resonance Imaging," the films described a "giant camera that takes pictures of your inside-parts." This approach was rooted in research with pediatric cancer survivors, whose real-life imaginary friends inspired many of the characters. To further bridge the gap between screen and reality, an AR app allowed children to project these friends onto actual hospital equipment, such as seeing a character "sit" on an MRI machine to make it less intimidating.

Global Scale and Honda Roots
The project originated from RPA’s long-standing relationship with Honda, a major supporter of the Pediatric Brain Tumor Foundation. What began as a domestic initiative quickly scaled into a global resource. The films were translated into 13 languages, including Mandarin and Arabic, and adopted by premier institutions like Children’s Hospital Los Angeles and Texas Children’s Hospital. Beyond digital media, the initiative manifested physically through thousands of user-submitted drawings that were transformed into dolls and posters for hospital rooms.

The project garnered international recognition from major industry publications like The Drum. Beyond digital content, the campaign resulted in tangible support tools including AR mobile app interactions, physical dolls for MRI machines, coloring books, journals, and inspirational posters distributed in hospitals. The initiative fostered a global community of support through social media character donations, creating a comprehensive ecosystem of care for pediatric cancer patients.
