Great stuff! Could you also upload the theme song intros for each season in the same HD quality please?

Trick or Treat Happy Halloween🎃🎃

Goosebumps, Animorphs, Are You Afraid of the Dark, William Shatner's A Twist In The Tale & Eerie Indiana were my favourite childhood scary programs. Thank you for a trip down Nostalgia Avenue.

I like to begin collecting my October tv shows early so when it hits October 1st, I just pop that USB drive full of my favorite Halloween shows in the back of my tv and let 'em rip!
This is my favorite series out of them all!

Goosebumps has and always will be part of my childhood. I watch them time and time again even at 26 years old lol. Thank god for the internet archives!

thank you so much for the upload. i have seen bits and pieces of episodes from various vhs tapes or tv show airings, but i was never able to see the show in its entirety.

My Grandma worked at a library for years, and she would bring home Goosebumps movies for me. The very first episode, the Haunted Mask brings me back to being a child. It's cool to watch these again.
