Well, I gave it a "B", because of Wilt "pretending" to be the bad guy. I know he's just pretending, but later on, it's getting too serious, and he's becoming more like the bad guy, because of the pretend. Okay, okay, and the way he said at the end, it's okay, but still disturbing. At least he's still kind, from noticing Goo all lonly at the beginning, and tried to make her be part of the act more. That is very sweet of him.
For some strange reason, I didn't even think about the part when Bloo ditched Mac. I just thought this is just the way plot is supposed to go. After all, Bloo is Bloo.
Now that Goo came back, it's becoming almost like her own episode!
And you got to admit, the "Goo riding On Coco" part was pretty cute.
So, that's why I gave it a "B". I was going to give it a "C" because of Wilt's part as a "pretend" evil villan, but there are other sweet parts, so I gave it a "B", instead.
