This new issuance is a 12-stamp sheet featuring Scooby-Doo helping out by watering a blossoming plant in a flowerpot — a simple act symbolizing a component of the “Doo Good” campaign’s effort to provide young people with tools and activities geared toward enriching the environment. The campaign, launching this year in partnership with generationOn, the youth division of Points of Light, also focuses on helping the hungry and acting as animal allies. The lovable, iconic Great Dane Scooby-Doo has solved mystery after spooky mystery since his 1969 debut. With his teenage friends — Fred, Daphne, Velma, and Shaggy — Scooby is at the heart of one of the most enduring cartoon franchises in television history. The charismatic canine has now fronted more than a dozen TV series, plus direct-to-video animated films, comic books and live-action cinematic releases. In Scooby-Doo’s comedy–mystery adventures, he and the gang investigate strange plots in eerie locales as they travel in their colorful van, the Mystery Machine. Scooby Snacks are always on hand; the tempting treats empower the cowardly Scooby to sniff out clues. Once the gang musters courage, cooperates, and persists in their dogged investigations, the spooky schemers’ plots are exposed. Three generations of fans have now embraced Scooby-Doo and the “meddling kids,” as they are often called by the villains unmasked at the conclusion of each Scooby-Doo mystery.
