Robin's heaven came from Mork (Mork spoilers)

I bought the first two seasons of Mork and Mindy. I watch the Season 2 premiere where Mork takes cold medicine and it causes him to shrink. It is a great episode and creepy one too because in the episode he shrinks so small that he ends up in a parallel micro world. The world is ruled by an evil king played by Tom Poston who was Mr Bickley in the series. The leader of the rebellion was Mandy played by Pam Dawber who was Mindy in the series. When Mork falls into this world it reminded me of how he fell into the heaven he ended up in in this movie. I was so shocked of how similar and that is when I realized that the heaven was inspired by this movie. Anyway what happens in the episode is Mork becomes the court jester to the king to spy on him for the rebellion only he is called the court serious because his job was to do the opposite of the Jester. The king hates laughter so he makes humor illegal so this role makes sense that he is suppose to keep the king serious and that is really funny. Mandy gets found out as the rebellion leader and gets captured. So Mork and 3 of the rebels are trying to rescue her. during the rescue the rebellion begins to attack the castle. Mandy gets killed in the crossfire. The emotions Mork feels when he sees Mandy dies makes him grow back to original size. When Mork is reunited with Mindy he says to her that he wants to leave Earth first so he doesn't lose her again. That is eerie because Robin is dead now and Pam is still alive.
