The Shop was the Pet Shop of Horrors.Confirmed from the manga's point of view, more or less - Count D is seen selling something in a box that sings quietly to itself, and he tells the customer those three rules within the first few pages of volume one. Being D, he's smug and amused that it all went horrifically wrong, and he is not helpful in the least.
The alignment of mogwai depends on their origin.If a mogwai (or possibly gremlin) is subjected to water against their will, then the resulting puppies are "evil" because of the trauma the original mogwai was put through. If a mogwai is prepared or has a proper partner, and is able to focus on their alignment or offspring, then the offspring are good or the same alignment as their parent. The other mogwai all turned out evil because Gizmo is single, asexual, adolescent, or just plain didn't want kids.
Gremlins are not Always Chaotic Evil.We've only seen "evil" mogwai aside from Gizmo, and Gizmo never had food after midnight. Who's to say that good mogwai wouldn't turn into good gremlins?
The Christmas presents scene in the first movie was a commentary on the rise of modern technology usurping the place of traditional entertainment.The new mogwai are all gathered around and fighting for control over a miniature arcade machine. Gizmo is playing a toy trumpet, and one of the other mogwai either spits at or intentionally projectile vomits at him in disdain to make him stop. The modern technologies are crude but popular, and they overshadow more traditional venues which, though they may be performed by less talented people, have heart.
Mogwai are Always Chaotic Evil.Gizmo is an exception, or the First mogwai.
The Shop was The Little Shop That Wasn't There Yesterday.The dad wasn't able to find the shop without bribing the kid to tell him where it was, and it was most likely in Chinatown, in San Fransisco. In the second film, the shop was in New York in what appeared to be an English-speaking district. The shopkeeper wouldn't sell the place; but if he had only been there for a couple of years, why wouldn't he? The answer is, he didn't move- the shop did. When he died, the shop became a perfectly normal shop that could be destroyed by a wrecking ball.
The Gremlins (and possibly mogwai) are arthropods, not mammals.The "fur" is soft spines used for identification (why Stripe and, until Brain Gremlin, Mohawk were the leaders of the Other Mogwai and gremlins); the skin is a soft but tough material, analogous to an insect's skeleton in the way that a snapping turtle's is compared to a slider or tortoise. Seriously, just look at the first shot of the pods, the hatching, and their fingers.
Mogwai in their mature form look like humans.The shopkeeper's mouth puffed out and wrinkled like Gizmo's when he said "I told you so" at the end, and had the hair sticking out everywhere. Gizmo can make sounds in English (most notably, "uh-oh"); and if Gizmo is the shopkeeper's son, and the other mogwai are evil because Gizmo is an adolescent as in the guess above, it kind of makes sense.
Mogwai in their mature form look like Yoda and Yaddle.Shave a mogwai and paint it green. Yoda. The living-on-Dagoba thing was possible because either Mogwai grow out of the multiplication when continually exposed to water or Yoda's just that good. (He's also an elderly wizard with no past.)
Grandpa Fred is PalpatineAnd he was the one who was really behind the electrocution of the Gremlins at the end. Also, Dr Catheter survived and hitched a ride from the aliens who created the Mogwai (in the book) to a galaxy far, far away, gaining the power to project electricity from his fingers.
Parts of the story were ghostwritten by David Icke.The Brain bears a suspicious resemblance to former Australian Prime Minister John Howard. Icke believes most of the world's leaders are reptilian creatures from outer space (in the book, the Mogwai were created by an alien scientist). Coincidence?
Mogwai reproduce sexually to produce "good" Mogwai, and reproduce asexually through water to produce "bad" MogwaiGizmo is the product of a male/female sexual relationship. There are female Mogwai around somewhere, but are very rare. - This is a headcanon, given that Gremlins have no visible genitalia, and the only way for them to breed given to us by the movies is the water reproduction.
Mogwai are based off a real animal, at least partiallyThey closely resemble tarsiers in their appearance.
Murray Futterman's stories about gremlins during World War II actually happened.They may have been the same gremlins as in the movies. Mr. Wing left his home country China when the Japanese started attacking. He took the Mogwai with him. On his way to America, Gizmo accidentally gotten wet and eventually came gremlins. Those gremlins may have gotten into American planes stationed in some countries along the way.
Gremlins are a sub-species of Orkz.They are basically smaller, animalistic Gretchens. They are also Always Chaotic Evil and naturally have some knowledge about machinery (which they use for sabotage), like an Ork. And they're green, just a little darker...
Gremlins takes place in the same world as Who Framed Roger Rabbit.Mogwai/Gremlins are proto-toons, what the toons evolved from. Or, alternately, they share a common ancestor.
