* DancingBear: Part of why this game is a CultClassic and has attracted an audience is due to how good the game is at simulating conversions with a non-human creature. As well as the sheer weirdness of said creature and the conversions themselves. Helping is the fact of it being one of the first ever games to use speech recognition.
* FanNickname: Some people nicknamed this game as ''[[WesternAnimation/FindingNemo Finding]] [[Creator/LeonardNimoy Nimoy]]''.
* SugarWiki/FunnyMoments: Every conversation with your Seamen has the potential to be this.
** Ebolaworld's [[https://www.youtube.com/watch?v=Y4MqvIHxkQo&feature=relmfu "Messing With Seamen"]] [[VitriolicBestBuds saga.]]
* SugarWiki/HeartwarmingMoments: Seaman's final monologue.
-->''You know, you're alright. I know we've had our differences occasionally, but I like you. You took care of me all this time and well, I'm...grateful. Very grateful.''
* NightmareFuel: ''Seaman'' is a game about nature, and nature isn't always pretty. Such is the case with the Seamen's first evolutionary stage after hatching: the Mushroomer. A nearby Nautilus squid will eat the Mushroomers, then after some time, will begin to twitch slightly, then start shooting out ink with regularity. Eventually, after it emerges from its shell, the ink it shoots will become a distinct reddish hue as it writhes in agony before the Seamen, now in their child-like Gillman form, pop out of the squid-like fishy [[Film/{{Alien}} chest-bursters]].
** The WebVideo/AngryVideoGameNerd was ''terrified'' by this. And by the Seamen themselves.
* OlderThanTheyThink: The Seamen may look like they were made on drugs but the design of the Seamen is strikingly similar to the aquarium scenes in Film/MontyPythonsTheMeaningOfLife.
* ScrappyMechanic: Adjusting the heat is a one-way road, so if you overshoot the ideal temperature sweet spot from the heater's odd momentum-based controls, you have to sit and listen to the Seamen crying in discomfort until it gradually lowers over time.
* {{Squick}}: The Seamen mating.
* TheWoobie: That poor nautilus...
