Caleb is accustomed to visiting Children's. Caleb's parents resorted to Children's and, most recently, the Aflac Cancer & Blood Disorders Center for his care when he was identified as having cystic fibrosis 12 years ago and thyroid cancer earlier this year. Caleb just received an unexpected surprise during his therapy. He got to say hello to Pikachu, his favorite Pokémon, as he was leaving the hospital.
