Looks like a good episode! Though idk if it's just me, but the animation and the overall vibe of the episode seems a bit different than the others?
The vibe of the episode is surely different, but I don't think the animation is. There are in fact two styles/qualities of animation in this show, depending on which of two South Korean animation studios was involved (Digital eMation - the Scooby Doo veteran and Yeson Entertainment - this is their first contact with the Scooby Doo franchise).
Interesting preview clips. Looking forward to this episode! Just in time for Batman Day this Saturday (although it won't be up online in time to watch it then, still waiting for episode 12 to be uploaded).
