"Scooby-Doo! Mecha Mutt Menace" is an animated short film from 2013, so now almost five years old and this one was directed by Emmy nominee Michael Goguen and written by Rick Copp, who worked on other Scooby-Doo projects. And there we already have the title character as this is of course another Scooby Doo short. That also means of course it has Frank Welker in it. I am a bit surprised how there are here and there always new Scooby cartoons coming out, but it shows how popular the characters are still today, so many decades after the premiere. Sadly, this one here despite going for the successful formulas is not really working out. The mystery story is so-so at best, while the comedy is disappointing. It's rare for a Scooby Doo film, but it was never really funny this time. Scooby is haunted by another canine this time, even if it is just a big robot, but you could say that this one takes Scooby into the 21st century I guess technology-wise. With shortcomings in other fields though and that is why I don't recommend the watch here. Only for Scooby completionists. I give it a thumbs-down.
