I take it that most of you have not explored the sea that much. while the pego can steal stuff and you have a fair chance of getting items back. the cnidaria totally wrecks you. even worse when you're fighting against an alpha mosa/ squid. they now aggro towards you even if you are on a mosa.
imagine getting dismounted while fighting a foe with big AOE, to add salt to the injury, it more or less perma stuns your tame. let's just say it's not only that the squid inks while in battle, most of the time my scuba leggings are brown in colour.
