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:
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.
