The coolest saltwater item you have owned

In general, I've found hitch hikers as interesting as the livestock I've purchased.

Mine was my Snowflake eel, Unagi. 

 

He would play in my fingers, curling around them and just hanging out. 

He jumped. 

 

I had that happen once. Big snowflake. Found him the next morning hard as a rock and dry as a bone. Went to pick him up to dispose and he started wiggling! Threw him back in and he was fine. Ended up giving him away a few months later.
