The studio's employee Junior, an avid fan of horror films, welcomes them and offers to give them a tour.
Brickton then casts TV show talk host Drella Diabolique as the female lead, to Daphne's dismay.
After Scooby has a wild ride on the plane and the monsters disappear, Brickton reluctantly signs the studio over to Fink, to Junior's sadness.
Velma mentions that the Headless Horseman and the zombie appeared at the same time, meaning the ghost of Boris Karnak cannot be in two places at once.
The gang heads back to the studio and with Drella's help and Fred's elaborate trap, they catch the zombie and the Headless Horseman.
They then realize that the security cameras have recorded the gang being chased by the monsters and decide to make a found footage movie.
Renee Longstreet for Common Sense Media gave the film a two out of five star rating and commented, "It must be difficult to retain the camaraderie and silly tone of the Scooby-Doo clan using hard-edged Lego bricks, and these filmmakers have not quite mastered it.
Ghosts and otherworldly beings in the franchise cartoons have a larger-than-life, shadowy, and fluid feel to them; these little boxy monsters are simply small molded toys.
Still, fans (and their families who don't mind a continuing onslaught of new toys and DVDs to buy in ever-changing incarnations) may enjoy the usual antics of Scooby and company, even in this latest "acrylonitrile butadiene styrene" form.
