About the collector, make it use its tentacles more!!

I believe the collector should use its tentacles more as it looks incredibly off how it flais them around, and possibly make it move like and actual squid, looking flatish and floaty while its passive and not attacking, and my most important point, let it reach out its tentacles like its lazy maybe! like itll try to catch you instead of moving too much due to its size.. and also let it use it to maneuver around rucks and boulders too making it harder to escape without leaving entirely.
