Hello. My nieces found these egg(bubbles) in a scummy NewJersey pond off a creek. It'd be great if somebody could identify the pictures. My initial research gave me the inkling they could be NJ Chorus Frog. This might be something else. Who knows?

The image upload did not work on my cell phone. It also did not work on the computer. Here is the link to take you to the picture of who-can-tell-me-what.
