How to make a tube full of tentacles?

Hello, I’ve been asked to make what would look like a tube full of kind of tentacles in its interior walls. So the tube will be animated in a wave style along its section and also all those tentacles will flow. Maybe this video explains better what I need to achieve:

As you see, the intestine stretches and expands in a waving like motion. Apart from that, in a detailed view the ilea (all those small tentacles that look like a rug) moves like grass in the wind. So I’ve been doing some tests with hair from object on a surface that gets deformed with a lattice.

To make it harder, at some point some of those will deform/degenerate and its colour will also shift to a darker one.

What do you think it’s best to get this done?

you can first make a basic cylindrical shape and subdivide it, then you can do a checker select and extrude those panels, then “crtl + numpadPlus” and hide all the panels involved with the extrusion you just made, then press a to select the remaining visible panels and repeat.
