It was great!! I did expect it to be obvious and it was towards the middle, but that didn't take me aback, I liked it a lot! Scrappy is just A-DO-RA-BLE! And the way he is the tiny troublemaker is hilarious!
I really liked the comic-book setting, especially as someone who reads comics. The Blue Scarab was actually a pretty neat villain. Scrappy was annoying as expected though, but thankfully I found the rest of the episode to be pretty good.
