This really depends on what species of Sea Cucumbers you're referring to. The fluffy end of Pyukumuku is probably there to give it a rabbit appearance, similar to that of a real animal, a sea slug aptly named Sea Bunny (Jorunna parva). Pyukumuku holds it's branching tentacles within itself and forces it out when in use, as most sea cucumbers do.
