I saw my first squid in Minecraft today and it scared me. I have mine on peaceful because I don't want to die when I'm building things, and I was digging my subway underwater. And a black tentacle was moving from the roof and I freaked out. Then I broke the tile (because I thought it was evil) and a thing (at the time I thought it was a monster, sent to kill me) came down, I got really panicked and killed it with my diamond axe. Then I picked up the ink sac and I'm like "oh that was only a squid". xD
