Editing Day of the Tentacle (section)

== Plot ==
Five years after the events of ''Maniac Mansion'', Purple Tentacle—a mutant monster and lab assistant created by [[mad scientist]] Dr. Fred Edison—drinks toxic sludge from a river behind Dr. Fred's laboratory. The sludge causes him to grow a pair of flipper-like arms, develop vastly increased intelligence, and have a thirst for global domination.<ref>{{cite video game |title=Day of the Tentacle |developer=LucasArts |date=June 1993 |platform=DOS |quote='''Purple Tentacle:''' It makes me feel great! Smarter! More aggressive! I feel like I could... like I could... like I could... TAKE ON THE WORLD!!!}}</ref> Dr. Fred plans to resolve the issue by killing Purple Tentacle and his harmless, friendly brother Green Tentacle, but Green Tentacle sends a plea of help to his old friend, the [[nerd]] Bernard Bernoulli. Bernard travels to the Edison family motel with his two housemates, deranged [[medical student]] Laverne and [[roadie]] Hoagie, and frees the tentacles. Purple Tentacle escapes to resume his quest to take over the world.<ref>{{cite video game |title=Day of the Tentacle |developer=LucasArts |date=June 1993 |platform=DOS |quote='''Bernard:''' Ok, you're free to go.<br />'''Green Tentacle:''' Thanks Bernard!<br />'''Purple Tentacle:''' Yes, thank you, naive human! Now I can finish taking over the world! Ha ha ha!<br />'''Green Tentacle:''' Wait!<br />'''Bernard:''' Oh, yeah. Now I remember. He's incredibly evil, isn't he?<br />'''Green Tentacle:''' Uh... I'll try to talk him out of it.}}</ref>

Since Purple Tentacle's plans are flawless and unstoppable, Dr. Fred decides to use his Chron-o-John time machines to send Bernard, Laverne, and Hoagie to the day before to turn off his Sludge-o-Matic machine, thereby preventing Purple Tentacle's exposure to the sludge.<ref>{{cite video game |title=Day of the Tentacle |developer=LucasArts |date=June 1993 |platform=DOS |quote='''Dr. Fred:''' Our only hope now is to turn off my Sludge-O-Matic machine and prevent the toxic mutagen from entering the river!<br />'''Bernard:''' Isn't it a little late for that, Doctor?<br />'''Dr. Fred:''' Of course! That's why I'll have to do it... YESTERDAY! To the time machine!}}</ref> However, because Dr. Fred used an imitation diamond rather than a real diamond as a power source for the time machine, the Chron-o-Johns break down in operation. Laverne is sent 200 years in the future, where humanity has been enslaved and Purple Tentacle rules the world from the Edison mansion, while Hoagie is dropped 200 years in the past, where the motel is being used by the [[Founding Fathers of the United States|Founding Fathers]] as a retreat to write the [[United States Constitution]]. Bernard is returned to the present. To salvage Dr. Fred's plan, Bernard must acquire a replacement diamond for the time machine, while both Hoagie and Laverne must restore power to their respective Chron-o-John pods by plugging them in.<ref>{{cite video game |title=Day of the Tentacle |developer=LucasArts |date=June 1993 |platform=DOS |quote='''Dr. Fred:''' My dials say that the larger specimen landed two hundred years in the past and the other is stuck two hundred years in the future!<br />'''Bernard:''' Well, hurry up and bring them back! <br />'''Dr. Fred:''' I will, as soon as I get a new diamond! Then all your buddies have to do is plug in their respective Chron-o-Johns and—<br />'''Bernard:''' Plug them in?!? Where is Hoagie going to find an electrical outlet two hundred years in the past!?!<br />'''Dr. Fred:''' Yes... well... He'll be needing my patented superbattery then, won't he?}}</ref> To overcome the lack of electricity in the past, Hoagie recruits the help of [[Benjamin Franklin]] and Dr. Fred's ancestor, Red Edison, to build a [[Battery (electricity)|superbattery]] to power his pod, while Laverne evades capture by the tentacles long enough to run an [[extension cord]] to her unit. The three send small objects back and forth in time through the Chron-o-Johns and make changes to history to help the others complete their tasks.

Eventually, Bernard uses Dr. Fred's family fortune of [[royalties]] from the use of their likeness in ''Maniac Mansion'' to purchase a real diamond, while his friends manage to power their Chron-o-Johns. Soon, the three are reunited in the present. Purple Tentacle arrives, hijacks a Chron-o-John, and takes it to the previous day to prevent them from turning off the sludge machine; he is pursued by Green Tentacle in another pod.<ref>{{cite video game |title=Day of the Tentacle |developer=LucasArts |date=June 1993 |platform=DOS |quote='''Purple Tentacle:''' You can't turn off the machine if I get there first!<br />'''Laverne:''' Uh-oh!<br />'''Green Tentacle:''' Don't worry guys! This time I know I can stop him!}}</ref> With only one Chron-o-John pod left, Bernard, Hoagie, and Laverne use it to pursue the tentacles to the previous day, while Dr. Fred uselessly tries to warn them of using the pod together, referencing the film ''[[The Fly (1958 film)|The Fly]]''. Upon arriving, the trio exit the pod only to discover that they have been turned into a three-headed monster, their bodies merging into one during the transfer. Meanwhile, Purple Tentacle has used the time machine to bring countless versions of himself from different moments in time to the same day to prevent the Sludge-o-Matic from being deactivated.<ref>{{cite video game |title=Day of the Tentacle |developer=LucasArts |date=June 1993 |platform=DOS |quote='''Purple Tentacle:''' You see, I've been busy. These are all versions of myself from the future. I've been bringing them back here using the Chron-o-John. Together we will conquer the world!!}}</ref> Bernard and his friends defeat the Purple Tentacles guarding the Sludge-o-Matic, turn off the machine, and prevent the whole series of events from ever happening. Returning to the present, Dr. Fred discovers that the three have not been turned into a monster at all but have just gotten stuck in the same set of clothes; they are then ordered by Dr. Fred to get out of his house. The game ends with the credits rolling over a tentacle-shaped American flag, one of the more significant results of their tampering in history.
