wait bug that can do...umm...
and they are usually around what parts of the forest you mention by the way? >///<

Ahaha
I wonder if they're further in past where the hypno snakes live...?

Oh, that looks like a very interesting creature. I do wonder what these creatures are. Why do they steal the brain juice? Do they eat it or is it for other purposes (just to see the funny expressions ponies make?)? Does one even realize what's happening to them? Or what it's like, because that expression looks like it's a pretty nice experience. :D Is it permanent or just themporary? I'd definitely be curious to learn more about them. Or see them appear again in the future. Cool concept. ;)

Thank you! I'm glad ytou liek the concept
the idea is that they become temporarily intangible and can fly throug ha pony's head and use gtheir magic to turn the pony's thoughts and energy into a kind of substance they extract into their abdomen that fuels them like food over time.
The effect is temporary on ponies, but it leaves them totally zonked out and hypnotised in the meantime, as the residual effect of the creature's magic fills the empty space with jsut swirling hypnotic magic leavng them with empty thoughts.

Eventually they recover and get back to their senses but will be a bit dazed for a while.
