As it stands I'm going to maintain my vote on Pie and urge investigation into Croc. As others said, Croc may be faking his role, although I initially didn't give it much thought because he has been very consistent.
Here is a quote from a previous post of mine on Croc:
"I'm a bit skeptical of jumping on the lynch train right now. Croc may have not done himself any favors being lurky but Croc's role and results make sense. Croc also hinted before at being Kakashi (remember when he said "I am Naruto's teacher") So at least he's been consistent. IDK, maybe I'm just not sensing something here that others are. Anyway, he is a viable candidate for roleblock... Just to see what happens."
However, what I didn't really think about was there are at least 4 teachers of Naruto in the series.
It's a very smart breadcrumb for a mafia because, as the game progresses, he can figure out which of these characters would or wouldn't get counterclaimed. I'm not sure if Croc has a history of coming up with really smart fake claims, but this would've been a great one. It's at least worth the look.
Another thing, I am skeptical of skittlez and his Rock Lee claim. Rock Lee is one of the most popular characters in the entire series.. I would think he gets a better role than "vanilla."
