I just realized something. 

Niffty and Agatha have some things in common. 

They're both kid-like, crazy and they were both maids....sort of. 

Agatha was the maid's daughter while Niffty is the maid of the hotel and was a maid when she was alive back in the fifties. 

Not to mention their hairstyles look similar.

Do you think there's a connection between those two? 

Then again, they were around in different times so I don't know.
