Scooby-Doo! and the Beach Beastie

They arrive at Daphne Blake's uncle Sandy Blake's seaside hotel in Florida, hoping the break will ease Fred's nets-obsessed mindset. The sunny retreat buzzes with vacation energy, yet locals hint at hidden tensions beneath the surface. The Mystery Inc. crew settles in, unknowingly stepping toward a mystery that will test their friendship.

A shape-shifting sea monster begins raiding the hotel property for jewelry, turning the vacation into a nightmare. Fred's net-based traps fail to capture it on the first encounter, hardening his fixation. The threat keeps guests anxious and the gang focused on protecting everyone while unraveling the mystery.

Fred's nets fail again and his fixation grows, fueling comic tension within the group. Daphne tries to steer him toward nets-free zones in a bid for calm, but the resort environment remains saturated with nets. The monster's raids continue to loom over the vacation mood.

Meanwhile, Daphne tries to promote a nets-free pace, but the lobby and beach are cluttered with nets, underscoring Fred's stubborn crusade. Locals whisper about the latest attacks, suggesting there is a deeper problem behind the disturbances. The team stays vigilant, protecting guests while continuing to investigate.

Velma heads next door to Kurt's hotel, where competition between the properties heats up and sets a rival dynamic. Kurt seems amused by the mayhem as repairs to the holographic water show stall, hinting that Brownstone Industries is dragging its wheels. The town's fate feels tied to the corporate delays behind the seaside spectacle.

Shaggy feels neglected as Scooby spends time with Shana, a guest's dog. He confides in Kiki Brownstone, wife of Grafton, sharing his loneliness and concern. The personal tensions mirror the larger mystery and start to braid the group's relationships with the case.

Shana's bond with Scooby deepens the dog-driven dynamic, while Kiki's loneliness adds a human thread to the mystery. Scooby's companionship with the dog keeps Shaggy's attention focused on the case. These emotional currents quietly influence how the investigation unfolds.

During a lively hotel party, the monster returns and again targets Kiki's necklace. The gang improvises a trap around the party space to lure the creature into view. The tension spikes as Velma becomes a direct target, raising the stakes for the investigators.

The trap, built from video cassettes, snaps the monster into sight and tightens the net around it. The creature's tentacle lunges for Velma, heightening danger and showing the plan's effectiveness. The team resolves to push further to uncover the truth behind the seaside attacks.

Fred reveals the culprit: Grafton Brownstone orchestrated the scheme, selling Kiki's necklace for money while the real one stays hidden. The necklace Kiki wears turns out to be fake, exposing Grafton's deception. His arrest marks a turning point as the truth behind the attack is finally uncovered.

With Grafton in custody, Kiki and Shana seek bail for him while Scooby and Shaggy rediscover their partnership. The group cements their friendship and refocuses on how to read beyond flashy distractions. The investigation concludes with renewed loyalty and a sense of unity.

The Florida getaway ends with the Mystery Inc. team reflecting on nets, both literal and metaphorical, and their improved ability to seek truth beyond flashy distractions. The seaside town settles back into a calmer rhythm, enriched by the lesson that trust matters as much as bravery. The gang leaves with a renewed sense of teamwork and readiness for the next mystery.
