I have seen a few reports involving squids emitting dark blue bubble particles instead of a light blue normal bubble. However, as seen on Java Edition, they strictly emit ink particles, and no dark blue bubbles. So I propose this different bug report on how squids emit dark blue bubble particles exclusively on Bedrock Edition. This could just be a parity issue on Java Edition's end, but I will keep this as a bug report to seek information.
Steps to Reproduce:
1. Find, summon, or spawn a squid.
2. Hurt the squid.
Expected Results:
Squids only emit ink particles when hurt.
Observed Results:
Squids emit dark blue bubble particles (and their usual ink) when attacked.

In my personal opinion, I'm not a big fan of the dark blue bubbles and would like to see them removed, but that would be a feature request, and this is the bug report site.
Thank you for your report!

Hello, I would like to confirm that this is a different bug. The bug that this was "marked as a duplicate" for is separate from this bug. This bug states that on Java, Squids do not emit these bubble particles, but bedrock does. This report doesn't have to do anything with the color of the bubbles. I ask in hope to reopen this report, if you please.
