If you've seen the shapes of the tentacles in MC:SM, you've thought about changing the tentacle model to look like in MC:SM, instead of being made of simple rectangles, it's made of several little squares placed randomly, like in the image:

Any updates on this?

Models will most likely be staying the same, however still needs further reviewing.

Should be a separate client option since this means more advanced models

i honestly like the idea of better tentacles

Yeah, going to be keeping the models the same. The current ones are too recognizable to be changed.
