I think it was probably very responsible for the Jubilant Entity to do. If I had disappeared without my bike, it could have hurt someone! And in my experience, teleportation and translocation tend to encompass whatever you happen to be touching at the time - including other people, but less non-mobile furniture. Unless the whole joint up and moves. And then it's fair game.
But I think the octopus and I came to a mutual understanding in the end, yeah. It wasn't an altogether traumatizing experience.
