Details are unclear because they don't exactly talk and I'm the only person I know so far with an interdimensional tentacle surprise, so far. It's hard to compare notes. I think it's one thing with a lot of fairly independent arms and maybe more than one head, and I've read enough about cephalopods that that kind of tracks. But I'm more like their door over to this side.

[Tentacle chat is a fun, breezy icebreaker!]
