S2E2 The Hypnotist

During a children's show, a hypnotist accidentally puts Principal Prickly under a spell, making him believe he’s just a six-year-old boy. As the principal embraces his newfound childhood perspective, chaos ensues at school, turning the usual order upside down. The students, amused and bewildered, are caught between enjoying the playful antics of their “young” principal and worrying about the consequences of his childish behavior. The staff scrambles to find a way to reverse the hypnosis before things spiral out of control.
