Appeared in The Ghost Busters episode"Merlin, the Magician", The Ghost Busters episode"Which Witch is Which?"
Played by Huntz Hall

Gronk is in the episodes Which Witch is Which?, and Merlin, the Magician making him the only character other than the main stars to appear in more than one episode.


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".

Physical DescriptionEdit


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.
