Goosebumps (1995)

You Can't Scare Me! - S2-E7

Continuity mistake: When the bullies put the snake in Courtney's bag, it's brown. When Finley takes it out, it's changed to black, and is also a rubber snake. And when Courtney picks it up, it's real again, and is now yellow.

The Haunted Mask (1) - S1-E1

Trivia: According to R.L. Stine's autobiography, they were going to use a rubber worm in the scene where Carly Beth bites into the sandwich and finds a half-bitten worm, but Kathryn Long insisted on eating a real worm to make it realistic.

Show generally

Question: At the start of every episode, it shows a man dressed in black carrying a black briefcase with the name R.L. Stine on it. Is the man in black really R.L. Stine or a crew member, and we are meant to only think it's Stine?
