Loud or startling sounds

Episodes to know about

Loud or startling soundsMystery Sound segment (recurring across episodes)Mild

Each episode features a brief mystery-sound game where an unidentified audio clip plays; sounds can be abrupt or unexpected, which may momentarily startle very young or sound-sensitive listeners.

Scary imageryHoax Hunters recurring segments (multiple episodes)

A recurring Hoax Hunters segment examines spooky-sounding legends and strange footage (e.g., the Fresno Nightcrawler mystery); it is handled with humor and skepticism rather than fright, making it a fun conversation starter about critical thinking and how to evaluate unusual claims.

Big emotionsBody science and puberty-adjacent episodes (various, later in the run)

Some episodes touch on bodies, bodily functions (digestion, smells, growing up), and related science in a matter-of-fact, age-appropriate way; nothing graphic, but worth a heads-up if you prefer to introduce those topics yourself first.
