The film contains no LGBTQ+ characters or themes. The mystery focuses entirely on Snoopy and Woodstock, offering no queer-coded subtext or identity-based exploration.

Lucy van Pelt displays significant agency and assertiveness, often dominating interpersonal dynamics. However, these actions align with traditional 'bossy' tropes rather than subverting gendered power structures.

The ensemble cast reflects a homogeneous lens consistent with 1970s animation. Characters lean toward a Western norm, lacking diverse ethnic identities or intentional intersectional casting.

The story reinforces conventional middle-class suburban norms and social stability. It presents a world of predictable interactions and gentle morality without deconstructing Western institutions.

Charlie Brown’s social anxiety is treated as a comedic personality trait. The narrative lacks a focused exploration of neurodivergence or disability as a central driver.
