Shirley the Loon appears in Tiny Toon Adventures, the Warner Bros. animated series that reimagined the Looney Tunes world through a younger cast of cartoon students at Acme Looniversity. Shirley is the group's dreamy, spiritual loon, often shown meditating or speaking in a calm, otherworldly manner that contrasts with the show's fast slapstick humour. Short clips of her chanting have circulated online as reaction sounds because the line is instantly recognisable to fans of the series and works even without the visual, turning a moment of cartoon zen into a joke about embracing one's own eccentricity.
