You know what was more disturbing than mutiny on the windbreaker?

It was Gene thinking he was having a romantic affair with a purple female manatee puppet. Disturbing on too many levels, almost too many to list!

Every post I've ever read anywhere about this particular episode always says Bob is right, and the captain was crazy! They are prisoners, this a slave ship!
Very offensive writing by the way to say 'Slave ship,' out loud, I am African American--black and you have no idea what my ancestors did for yours!
That doesn't explain why the captain still had his license and ship, and the people taking the cruise voluntarily boarded and were there for freewill...

I digress.
So let's dissect the subplot instead. First of all, Louise and her nails. Beautiful. What, you thought I'd be like --Ah! Shriek! Disturbing! --no. They were her personal choice with her body. Everybody is entitled to that.
What actually is --Ah! Shriek! Disturbing! is Eugene's infatuation with a muppet. First, I guess they tried to soften the blow with that by creating a manatee version of Miss Piggy, by making it cartoony and like one of the actual muppets it draws away from some sort of bestial tolerance. If it was realistic like a real manatee --it would be a nod for bestiality an equally disturbing fetish.
Puppet fetish people are called Agalmatophilia. The attraction may include a desire for actual sexual contact with the object, a fantasy of having sexual (or non-sexual) encounters with an animate or inanimate instance of the preferred object, the act of watching encounters between such objects, or sexual pleasure gained from thoughts of being transformed or transforming another into the preferred object.
At first it seemed almost unreal and unnatural--unbelievable that Gene couldn't tell it wasn't real just cloth and buttons were enough to give him an erection, meanwhile Gene actually admits in the end that he knew she was just a puppet but she stuck her hand right up his heart....
Let's get back to Agalmatophilia, those are people you should stay away from,--just in a romantic sense not because they have an altered view on reality--that's part of it, but they can literally and physically hurt you. They're more likely to tie you up and request that you act out their fantasies, next thing you know, you're a marionette that's why!
So Gene runs around talking dirty about a puppet---that's something else. It wasn't just like a few mentions either and the closest anyone gets to addressing how unnatural it is to fall in love with an animal and a stuffed animal at that is the comment that there aren't many manatees are not in the ocean because they are endangered species. Thankfully, Marilyn the manatee is not brought up again.

But what's the difference between that and Tina's imaginary horse Jericho? Simple. Jericho doesn't exist. He is a reflection in Tina's mind, also giving her an altered sense of reality a fantasy which may or may not be healthy--no she cannot date this horse for two reasons:

1. It would be bestial

2. It doesn't exist at all
