Spocktopus. It really speaks for itself, but maker Catharina Torres explains his origins:

A friend of mine said she didn’t like the plush octopus that I recently made. She is a major Star Trek fan. So I thought that if I made an octopus combined with her love of ST, I could change her mind for sure! Out of that……Spock-topus was born! (Yes….she loves him :)
