-->-- '''Seaman''', as an adult gillman

''Seaman'' is a virtual-pet-raising game released for the Sega Dreamcast in Japan in 1999 and localized in 2000. It was [[UpdatedRerelease re-released]] [[NoExportForYou for Japan]] as ''Christmas Seaman'' and again as a Playstation 2 port. [[WhatCouldHaveBeen There were also plans for a PC release that allowed Seaman to interact with and manipulate your desktop and e-mails,]] [[DummiedOut but it was eventually cancelled.]] A sequel was also released, [[NoExportForYou again, only in Japan]], for the Playstation 2. The game was one of the few in the Dreamcast library to take advantage of the microphone. It also features narration from Creator/LeonardNimoy in the English version.

You play as a pet owner who had decided to adopt a new, unknown species dubbed "Seaman" by scientist and discoverer, Jean Paul Gasse. The titular creature is a fish-like animal [[spoiler: gradually evolving into a frog-like creature]] with a human face who would eventually be able to talk with you. You start out with a handful of food pellets and a seaman egg to start with where you must hatch the egg and raise the resulting seaman [[spoiler: or rather, sea''men'']] to maturity. You are tasked with checking up on it to make sure it has enough air in its tank, the environment is warm and that they are fed, and eventually you'll be able to converse with the seaman and be asked various questions as you raise it. Although [[TrialAndErrorGameplay you are left to figure out how to raise the seaman on your own]], Nimoy will also give you general hints and tips as you check in on your seaman.

-----
!!This game provides examples of:

* ADateWithRosiePalms / AccidentalInnuendo - ''You'' try bringing up Seamen without someone cracking up.
** IntentionallyAwkwardTitle
* AllThereInTheManual - A good chunk of the backstory behind Seaman's creation are found in the instruction booklet, and although Seaman will occasionally shed light on his origins and his experience with Gasse he gradually recalls, it's only a quarter of what you could read in the manual.
* AwLookTheyReallyDoLoveEachOther - The seaman can act like a [[{{Jerkass}} smartass]] for most of the game when it's mature enough to learn back-talk, but he also occasionally shows care for you by complimenting you and calling you nicknames like "fuzzy".
* DeadpanSnarker - Seaman
* FictionalDocument - The Japanese marketing campaign had fake fossils displayed at museums, and even a ''book'' was published (''The Journal of Jean-Paul Gasse'').
* GuideDangIt - Some aspects in raising your seaman, partly for certain acts you're supposed to perform to allow them to evolve that you won't have a clue to do, and partially because the seaman's voice recognition is limited. [[spoiler: an example for the former includes how you're supposed to awaken the Nautilus (in the shell in the tank) and allow it to eat your mushroomers so they'll become gillman, while the latter includes the task of naming your seaman by specifically saying "I will give you a name." or "I will/shall name you.", because simply asking "name?" will ask if they ''have'' a name, and "do you want a name?" won't let you name them. Note that Nimoy will mention both of these eventually.]]
* HeyItsThatVoice - Besides Leonard Nimoy, the seamen (from the adult-gillman stage onward) are voiced by Jeff Kramer, the man responsible for [[VideoGame/DeadlyPremonition Agent York]]. Not George Takei, as popularly believed.
* {{Jerkass}} - Your seaman to you.
** Jacked up to eleven in the print ad:
-->'''Seaman on love:''' Don't make me vomit.
-->'''Seaman on the f-word:''' I'm too polite to use that word, so I'll say... "Bite me, you baboon-faced ass-scratcher."
-->'''Seaman on his astrological sign:''' I need a middle finger to show you.
* ProductPlacement - Try asking your seaman about Playstation, Nintendo or the Sega Dreamcast. [[spoiler: He also has a habit of trying to convince you to buy another Dreamcast]].
* SequelHook: One that never panned out. [[spoiler: The story of Seaman's origin and biological notes implied that there was another version - a bird with a human face created when mushroomers were eaten by waterfowl. At the end of Seaman 1, the Seaman - now in toad form - sets off to find this creature.]] [[AbortedArc The Japanese Seaman 2 was totally unrelated to this.]]
* ShoutOut: "You're a BraveLittleToaster, aren't you?"
* StarCrossedLovers - [[AllThereInTheManual Apparently]], Seaman was either the reincarnation or the descendant of a son of a pharaoh in the third dynasty of Egypt who fell in love with a priest's daughter. The priest had sought advice from the god of wisdom Thoth, who turned the pharaoh's son into a fish and the priest's daughter into a bird, both of whom vanished. The priest, who was in charge of the construction of the pyramids, built a landmark that served as a beacon to guide the two lovers back someday, and was nearby where Seaman would have been discovered centuries later by Gasse.
* TheDevTeamThinksOfEverything - A handful of the things Seaman can respond to, and a few cases of him remembering an old response you made to throw back at you later [[spoiler: such as [[RuleThirtyFour if you brought up you looked up porn on the internet]], and you answer you like the internet uncensored later, he'll remark that freedom of speech on the internet will at least get the pervert vote.]]
* TrialAndErrorGameplay - You only have a limited number of food pellets to feed your seaman with before you run out [[spoiler: and although you later can raise caterpillars and crickets, they too are limited]], and it is very easy to run out.
* UnwinnableByMistake - Use up your food pellets too soon [[spoiler: or use up all the caterpillars or crickets]] will lead to you being unable to get any more food, leaving your seaman to starve to death.
