What is growing on my rock?

Noticed these green balls starting to spread over my live rock. They are light green with a short clear tube coming from the center. Have searched to try and id them but with no luck. Figured someone here may know what they are.

Here are a couple pics, hopefully not too blurry.

Thanks

Sponges most likely. (harmless)
