Top 10 Misconceptions/Flaws of Scooby Doo! and the Reluctant Werewolf

When Count Dracula and his monsters tried to turn Shaggy into a Werewolf, it required an event every 500 years, where the Moon was in "perfect position" for 3 nights.

Obviously this is not true.

For the Moon to be in perfect position:

1. It must be full.

2. It must be at the opposite-most position from the Sun, where it reflects the Sun's light and we see it at maximum.

It's obviously not true for it to be in "perfect position" for all 3 nights, the Moon can't turn full for even a second, and once it reaches the opposite-most position from the Sun, it leaves, as it's constantly in orbit around the Earth-Moon Barycenter (which orbits the Solar System Barycenter), and therefore it's too late.

Therefore on the second night, right when it reached that perfect position", only was it then it was truly in the perfect position and full, so therefore on the first night, it was too early, and it hadn't really entered that ...more

The Hunch Bunch may have been monsters, but they looked more like humans who were hunchbacked and fat, while it was easier to tell one of them with the gross language, they still looked like humans rather than monsters, so it was not easy to expect them as monsters.

Since the movie was in 1988, technology was still kind of primitive.
Especially the holographic projection of Count Dracula.

Holograms weren't invented yet at that time, and his appearance around the race was done with a holographic projector by his mates.

Also we don't have the technology yet to invent a shrink ray, so there couldn't have been one in the movie since it was released in and took place in 1988.

In one part, Dracula detached the car engine, but Scooby and Shaggy pressed the button and it still worked.
And not to mention the air at the altitude of 35000 feet is -49 degrees Fahrenheit, so they'd freeze to death immediately.

When they flew out of the Tombstorm, and found out they were on First Class, they were really first class outside a Plane.

You can't ride outside a plane without attachments or protection, as the air outside it would blow you off, which didn't happen to them or their car.
Also they would've gotten Altitude Sickness from the low oxygen at that height and died.

The cars were fine, but some of them were made of food and could handle extreme conditions.
One of them was made of slime, another was made of mummywrap, and they were handled like real cars.

Obviously one can't drive a toilet paper or slime car, they would break apart before you even get in it.

There's NO way he can set up a new attempt to turn Shaggy into a werewolf that soon.

It can only be done once every 500 years, when the Moon's in "perfect position", and that's not possible either to have for 3 nights.
