* In the Christmas episode, the Ghostbusters trap the ghosts of Christmas Past, Present and Future all in one trap, and they all remain separate. But didn't another episode state that when you trap multiple ghosts in one trap, they end up permanently fused?
** That was "Drool, the Dog-faced Goblin." Um...okay, let's try to untangle this one. Drool and his Bigger Brother are "monster" ghosts; as such, they probably have low personal "integrities." That is to say, when locked in the trap, they fuse easily. The Christmas Ghosts, on the other hand, are personifications of Christmas, and their personal integrities are most likely pretty strong. Also, as revealed at the end of the episode, the Christmas Ghosts ''allowed'' themselves to be captured as part of their plan.
** This one has bothered me as well, especially in light of the fact that in the movie (the events of which are canon to the animated series) all the ghosts stuffed in the containment grid were able to separate after being trapped when the containment grid went nuclear (which is why we have Slimer running around), even though at one point in the film, foreshadowing the danger, Egon mentioned the super concentration of ectoplasm in the grid, implying compression. However, there is another possibility with the Ghosts of Christmas Past, Present, and Future. They may not be separate entities at all, but rather, all aspects of the same spirit. They wouldn't need to worry about separation, as they were already a connected entity to begin with.
** Several episodes are in contradiction with this. In ''Ghost ‘R’ Us'' a family of ghosts is trapped together and later seem separated, even inside the Containment Unit.
** The episode that used the plot device "multiple ghosts sealed in one trap fuse together" was the (glaring and illogical) exception, not the rule.
* In the climax of "Ragnarok and Roll," while the guys' plan to blow themselves and the villain up is noble and brave, how come none of them pointed out while agreeing to the plan that there were also two innocent bystanders on top of the building at the time? Yes, they had no choice, there were billions of lives at stake, they couldn't let that stop them, but still, it would've been nice if one of them had observed "But we'll take out the two of them, too" or told them to run for it (even though they probably would've refused).
** They had already pointed out that the explosion was going to take out several city blocks, and that there would be substantial collateral damage and civilian deaths, but that even wiping out lower Manhattan was better than the alternative. Presumably, the two bystanders on the building roof with them were included in that.
* Could someone tell me why the Ghostbusters had the Stay-Puft Marshmallow Man in the containment unit? This cartoon's supposed to have continuity with the movies, and the he wasn't trapped. He was blown up into marshmallow goo.
** The 2 prevalent fan theories are:
## It's another ghost, not Gozer, who took on that form, probably inspired by how an extremely powerful ghost took it on recently (supported by how his personality is nothing like Gozer's).
## The episode "Citizen Ghost" reveals that the Gozer-marshmallow-residue all over their uniforms was dangerous and needed to be disposed of (since Peter fails to do so, it turns into doppelgangers of the guys who nearly kill them). Thus, all the goo that rained down on NYC after the battle was just as dangerous, and the guys needed to dispose of it, too. How? By vacuuming it up and putting it in the Containment Unit, where it returned to its original form, albeit without the mind or personality of its maker (Gozer).
