This is a giant tentacle. I can't think of much more to say about it, other than to confess my admiration for shanev12's sheer determination in making the damn thing. They woke up one day, said "I want to have a giant tentacle in my house," and then turned their dream into reality. They also happened to fully document the process of creating "Larry", their name for the bespoke, and be-suckered, appendage.
You know, I don't like cheesy Mythos Christmas stuff. Tentacle ornaments? Plush Christmas Cthulhu? Blech. None for me, thanks.
But, as God is my witness, a giant tentacle covered in blinking lights and topped with a holiday star has to be one of the coolest things I've seen this year.
