Yeah, but Maude appeared as a ghost several times, which is why she's here. Also, Grimes died from electrocution, which can bring someone into coma, while I don't think Mona wouldn't be dead for real.

As a side note, Krusty's father appeared as a ghost during a Christmas opening, so maybe he could be here too.
