I'm looking for a legally free sound that sounds like Hypnotoad. Any ideas?
I tried some turbine sounds, and tried changing pitch, boosting the bass, and a few other things to the sounds I found, but didn't get anything I'm satisfied with. Can anyone think of a good sound to start with?

I would try some electronic current, "tesla coil"-sounds.
If you don't have a tesla coil at home, try the following library:
(site with great sound fx, awesome pay-what-you-can pricing model)
I would look for a short loop with only slight modulation to get the repetitive hypnotic feel. Maybe use a little pitching, then EQ out aggressive frequencies and use compression/saturation...
Might also worth to layer with some static noise or drone...
