Other mistake: When Cory and Shawn are auditioning for "Guys" and they're talking about the first person they pick, Cory says,"He's shorter than me and..." but after they pick both guys and he's talking to them, you can see that Cory is the shorter one.
Other mistake: After the teens leave the command center, Rita sees this and orders the creation of her Putties. Her henchman slaps down a few things of clay into a mold loosely, that then show the perfect figurines of the putties coming out of them. However with the shape of the mold, there is no way that the clay would come out in shapes like that or with that detail. (00:11:35)
Other mistake: In the scene where Yakko, Wakko and Dot are sitting at their desks repeating Miss Flamiel's every word, Wakko is drawn without legs (only feet) during one shot.
The Library - S3-E5
Other mistake: Dr. Mike spots a charred Bible within the charred piles of books, and heads into the church. The Reverend is giving a sermon on morality, and offers Dr. Mike the floor and she briefs about certain stories in the book, which would be considered scandalous, without mentioning the book's title, then hands it to the Reverend who agrees such stories are scandalous, until he turns it over, to see that its 'The Holy Bible'. Being a Reverend, he should know The Bible cover to cover, but reacts surprised or shocked over the mentioning of the scandalous stories. (00:36:00 - 00:41:00)
Suggested correction: Given that these are literal monsters and a witch living on the moon after being imprisoned for 10,000 years, I don't think we can say for certain what their machinery will do.

This is speculating too much. Practically making the same argument that it's OK because magic. The general physics of what is being displayed on the screen doesn't match up with how the clay fits into the mold even in the slightest.

What Quantom is saying is that they are using a press die to create the mold for the putties and no matter how you look at it, the volume of clay going into the mold is not enough to create the detail seen on the putties.

It's not just that, but the shapes don't match up at all. He does the equivalent of putting clay into a round hole and getting a square out of it.
