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.
