|Played by||Huntz Hall|
While he sometimes give the impression that he isn't all that bright, Gronk has moments that show he isn't stupid either. He shows hints at being a bit of a womanizer, as he is shown hitting on Morgan Le Fay in "Merlin, the Magician".
Oddly, neither the Ghostbusters or Gronk make any comment on his repeat appearance. However, in Ghostbusters it is noted that ghosts can come back after being Dematerializered.
