Do you mean hydroCOLONIC? That is similar to an enema. Where they insert a tube with water up your butt and use water to cleanse your colon. Its actually very effective. I imagine that is what shaggy was talking about.

So, the word isn't "hydroclonic". It is "Hydrocolonic". Shaggy and Scooby thought it might be something for weed, and checked it out, only to find out it was a water-based enema. That's why they don't go anywhere with that in the name.

I'm also watching Scooby-Doo & just Googled this to find out what it was hahaha . There's many secrets in this movie referring to weed & things like that so I just was curious what it meant hahaha

I've not seen this movie but I think you might just be referring to colon hydrotherapy - Hydrocolonic(sp?) I saw something about this on Current TV. I believe it consists of having a tube placed into your sphincter and then water is pumped in and out of your colon. Pretty funny picture, eh?

So, I guess its one way to have your colon cleansed. Sounds like fun

I'll add a link for source

Bruh tht movie has soooooo much secrets, tht were hella inappropriate fo lil kids Like how shaggy is constantly hungry, he is hella goofy like he's on something, he trips the MOST, and to add some more funkiness to it all... His best friend is a talkin dog. And in the movie on the plane shaggy meets a girl who tells him her name which is Mary Jane code for "marijuana" or "weed" and shaggy responds saying "that's my favorite name!"

I was just watching Scooby-Doo and was wondering the same thing and googled THIS! What a coincidence! I think it was something to do with food.

I just googled this because I was watching te Scoobt Doo movie too!!! Haha what a coincidence!!
