I don't really know if very many halloween episodes... So I'm just gonna pick one I know of. Check out @hikaymm who started this whole thing.
Episode 51 of Fairy Tail series two... Fairy Tail of Dead Meeeen. I don't know if this came out around halloween time or not but it definitely has a halloween feels to it. I'd recommend this to anybody who just wants to get a nice laugh out of their favorite characters in a weird situation.
Tell me about some Halloween themed episodes you know of cuz I hardly know any. (x
