Zombie Island | Scooby-doo On

Rating: ★★★★½ (4.5/5)
Best for: Scooby fans tired of the old formula, horror-comedy lovers, and anyone seeking a genuinely spooky animated film.
Skip if: You prefer your Scooby snacks without actual scares or real supernatural threats.

You cannot discuss this film without mentioning the music. While the chase songs ("The Ghost Is Here") are fun, the emotional core is the closing credits song, "Terror Time Again" by Skycycle. It is a grungy, angsty rock anthem that perfectly captures the film’s tone: nostalgic, angry, and terrified.

But the darker track is "It's Terror Time Again" (the diegetic song played by the zombie band on the bayou). It’s a fast-paced bluegrass horror tune that juxtaposes the joy of a party with the reality of an impending massacre. The score, composed by Steven Bramson, utilizes eerie choir vocals and deep cellos—sounds you’d expect in a Stephen King film, not a Scooby-Doo cartoon. Scooby-Doo on Zombie Island

The film opens with a meta-joke: Mystery Inc. (Fred, Daphne, Velma, Shaggy, and Scooby-Doo) has disbanded. It has been years since their last case. Fred is a G-Men agent, Velma owns a bookshop, and Shaggy and Scooby are airport security (a job they hilariously fail at). Daphne, now a successful TV investigative reporter, feels her career is stale—she’s tired of fake monsters. She decides to reunite the gang for a road trip to Louisiana to find a real ghost for her show.

The gang travels to the mysterious, fog-shrouded Moonscar Island in the bayou. They meet Lena Dupree, a beautiful but melancholic innkeeper, and her gruff, one-eyed boat captain, Simone Lenoir (who runs a popular pepper sauce company). The island is supposedly haunted by the ghosts of the pirate Captain Moonscar and his undead crew, who terrorize the locals every full moon. Rating: ★★★★½ (4

The first half of the film plays like classic Scooby-Doo: spooky chases, trap setups, and split-up searching. However, the zombies (decaying, moaning, glowing-eyed corpses) appear to be real. The gang attempts to unmask them, but when Velma rips off a zombie's arm, there is no Velcro—only rotting flesh and bone. They are genuinely terrified.

The second half reveals the truth, but not the traditional one. The "villains" are not the zombies, but Simone and Lena. They are not greedy real estate agents; they are 400-year-old werecats. Backstory: In the 18th century, Simone and Lena were voodoo priestesses who sought eternal life. They summoned a cat demon, which granted them immortality at a terrible cost—they would drain the life force of others to maintain it. They massacred the pirate crew of Captain Moonscar, who, in their dying moments, cursed Simone and Lena. The pirates’ souls were trapped between worlds, rising as zombies each full moon to warn outsiders away. While the chase songs ("The Ghost Is Here")

Simone and Lena have been luring tourists (and the Mystery Inc. gang) to the island to harvest their souls. The zombies, far from being villains, are tragic, cursed victims and the island's protectors. In the climactic battle, Shaggy and Scooby accidentally ingest a necklace of catnip, turning them into super-powered, Kung Fu-fighting werecats (comic relief). Fred, Daphne, and Velma use the zombies' own weakness (they dissolve in moonlight) against Simone and Lena, exposing them to the full moon. The werecats age 400 years in seconds and crumble to dust. The zombies, their curse finally broken, thank the gang and ascend to the afterlife, their souls at peace.

Unlike previous installments where the "spooky" elements were played for laughs, Zombie Island leans hard into atmospheric dread. The animation, handled by Mook Animation (the same studio behind Batman: The Animated Series), is lush, shadowy, and cinematic. The rain is relentless. The fog clings to the cypress trees. The zombies—hulking, green, rotting corpses with glowing yellow eyes—don't crack jokes. They groan. They claw through dirt. They chase the gang with a slow, implacable menace.

There is a specific scene that traumatized a generation of '90s kids. When Shaggy and Scooby hide in a closet, a zombie’s hand bursts through the door, throttling Shaggy. It’s violent, sudden, and completely unexpected. The film also includes a jump scare involving a cat named Jacques that rivals anything in Alien.

For the first time, the audience is scared with the characters, not at them.
