Egg mass of some sort. I want to believe it's a nudibranch of some sorts. Could be any mollusk. I have no idea. The top recommended ID is Colorful Aeolid but it doesn't match up with Google image results.

Some type of nudibranch or flatworm up in San Diego. Purple in color all over. Distinct slim main body with large flat foot completely surrounding it. It reminds me of a Brown-Striped Flatworm, but those are typically found in Singapore.

probably a long shot but this reminded me of the one I saw earlier this year. It could very well be just a dark homely aeolid but it does have dark bands along the foot. The cerrata aren’t quite as irregular though.

here is the observation I’m referencing:
