After solving their latest case, the gang feels they need some serious R&R. They decide to join in the annual fun at a nearby beach. When an argument in the Mystery Machine brings up Fred's (Frank Welker - because who else can voice Fred) and Velma's (Kate Micucci, Steven Universe, Nerdland) inability to have fun, the pair decide that they are going to show Daphne (Grey Griffin, The Grim Adventures of Billy & Mandy), Shaggy (Matthew Lillard, the Scooby-Doo movies) and Scooby-Doo (also voiced by Welker) that they can be just as fun-loving as the rest of the group. In fact, they proclaim that they will be crowned the King and Queen of the party, an event that happens at the end of each annual festival.
When the gang gets to the beach though, they find it deserted and quickly learn that a pair of ghost pirates, the same pirates that the party is in honor of, have appeared and stolen the pirate hats that are used as crowns. What starts off as a mystery to find the missing hats quickly escalates to kidnapped teens and a missing pirate ship. To make matters worse, a local businessman is trying to buy up all of the boardwalk property in order to expand his pier amusement park and make the town a year-round attraction instead of just the time around the seasonal event.
Blowout Beach Bash is filled with the standard Scooby-Doo tropes. Everything from music to chase scenes to traps and, of course, mask-unveilings will appear before this film is over, but as an added twist to the story's formula, you also get to see LEGO versions of Fred and Velma try to have fun while solving the case. In a bit of role reversal, Daphne, Shaggy and Scooby end up focusing on the case more while the other two are slacking off.
While LEGO Scooby-Doo!: Blowout Beach Bash doesn't contain any special features directly related to this movie, what it does have is three Scooby-Doo episodes that share themes found in Blowout Beach Bash. Two are from the classic Scooby-Doo, Where Are You! series and the third is from the more recent Be Cool, Scooby-Doo!. The classic episodes are "Go Away Ghost Ship" and "A Clue for Scooby-Doo" where the gang faces off against ghost pirates and a ghost diver, respectively. The third episode, "Party Like It's 1899," is all about a big party that is crashed by a ghost.
LEGO Scooby-Doo!: Blowout Beach Bash is a fun film that any Scooby fan will want to enjoy. The voice acting is solid (which is expected, given that each of the main actors is a veteran in their roles), the story feels like a typical Scooby mystery, and there are jokes a-plenty, especially LEGO-centric ones that is something common to the franchise. I can't say that the overall package is worth a purchase unless a young fan in your life is going to want to watch it over-and-over again, but it should definitely be checked out.
