Chuck the plantIn the mansion's library, there is an un-useable plant called "Chuck the Plant" The plant also appears in Indiana Jones and the Last Crusade in Henry's room, and Day of the Tentacle in the lobby.
Copy protectionThe computer versions featured an humorous copy protection scheme. In a new game a player entered the house, walked upstairs and are confronted by a giant iron bolted door which opens after entering four correct symbols on the keypad as shown in "Nuke'm Alarms - Nukes Burglars in their tracks: Owner's Disarmament Quick Reference Guide" included with the game. The wrong answer proved fatal!
Day of the TentacleManiac Mansion is included as a bonus game inside Day of the Tentacle (on Ed's computer).
Hamster in the microwavePlayers can microwave the hamster in any of the computer releases (but not the NES version), but they have to use a sick-minded character (such as Syd or Razor) when doing it. Showing the exploded hamster to Weird Ed will make him kill that character.
NES versionThe game was ported not once, but twice, to the NES. One version was made in America, while another one was made by Jaleco in Japan. The two versions look very different. It was one of the very few NES games to be translated into Spanish.
Many things had to be censored/changed to comply with Nintendo's policies:
- Some of the language was toned down, for example: "The meteor is going to be pissed" was changed to "The meteor is going to be mad."
- The "KILL THRILL" arcade game was changed to "TUNA"
- "For a good time EDNA 3444" was changed to "Call Edna 3444"
In the European NES version, additionally the possibility to wave the hamster was removed. In turn, at least in the German version, some linguistic points from the above list are closer to the original.
- The name of Razor's punk band is "Razor and the Scummettes", a reference to the SCUMM graphical interface used by LucasArts adventures.
- There is an X-Wing model in Ed's room.
- The speakers in the green tentacle's room are "THX" sound speakers. THX is a high-quality sound technology developed by Lucasfilm.
Zak McKrackenConnections between Maniac Mansion and Zak McKracken (based on Amiga version):
- In the game room there's a Zak McKracken poster.
- In Maniac Mansion there's a chainsaw that has no gas. In the game Zak McKracken there is a can of gas on Mars. The can reads, "For use with chainsaws only". When trying to pick it up the character says, "I don't need it. It's for a different game."
- "Tuna head" is said in both games. One of the aliens in Zak McKracken is always saying, "Tum de dum." In Maniac Mansion when Weird Ed is walking through the kitchen to get his cheese he says, "Tum te dum."
- It appears that Zak happens to be going out with Sandy from Maniac Mansion. In Zak McKracken, if players go away and come back home enough times and keep checking the answering machine they will soon get a message from Weird Ed from Maniac Mansion. He calls up about going to a monster truck show, and that he'll come by with Sandy at 6:00 in the Edsel.
- In Zak McKracken, at the police station in Nepal: there is a wanted poster for the purple meteor.
RemakeThe German LucasFan Games developed a freeware 256-colour remake called Maniac Mansion Deluxe.
TV seriesThe game spawned a comedy series on the Family Channel in the early 90's.
