Geckos make sounds? What, like squishy noises when you step on 'em?

"The Gecko's call is remarkably loud and clear and can be heard from a long distance; its popular name is derived from its call. Each call consists of a preliminary cackle, then the sound tuk-kaa repeated deliberately and distinctly several times."

I googled that up, it's a fair description. They are very loud. There are some around here that are over a foot long, they may be the ones with the loud voices. It spooked me the first time I heard it, couldn't see the lizard, didn't know what was making the noise. Once we came home and there was a big one on the wall on the side of the house, at about eye level. It growled at us when we approached it.
