According to Bustle:
ThePre-Lit Inflatable Animated Beetlejuice Sandwormself-inflates to stand around 9.5 feet tall and, according to the reviews, is a perfect likeness for the sandworm from the movie. It self-inflates for an easy setup and comes with stakes to make sure that your snake doesn’t go with it anywhere. It even comes with a motor installed to help the snake’s creepy tongue move around. Basically, this is themostepic of all epic floats.
It is available at Home Depot for $179. Worth it? I think so lol
