Make a dangerous mob that spawns in the under water caves

The new underwater caves aren’t that dangerous to explore. I like the idea of making exposed ores more common in them but there needs to be a threat in the underwater caves to make it a bigger risk for more rewards.(as opposed to now that it’s just a big reward) Drowned- this would be the easiest option because this mob already exists. Glow squid- here’s my ideas for making the glow squid a threat under water with out making it hostile in any way. When looking at a glow squid ur sensitivity and fov lowers down a lot and u swim much slower. Making them spawn in these caves would be a very good way to make them more dangerous.(maybe u can make goggles out of the amethyst shards to block the glow effects(we already have the tinted glass which can block the light, so it fits with the theme) plus making the drownd spawn in there as well will make it them a bigger threat because the glow squid will make it hard to protect ur self while the drownds attack u.
