From the Hollywood Costume Ideas File: Someone's dad went dressed as an "Aliens" power loader. It's the thing Ripley (Sigourney Weaver) was operating in the movie that looks like something you'd see stocking shelves at Costco. Now, when I mention it's someone's dad in this thing, I do need to mention that he rigged it so he can have a baby on board. You gotta love that!
According to the dad's YouTube post: "My Daughter and I went to a Halloween Party dressed as the Power Loader from "Aliens." I love Halloween, and I wanted to create a costume that my daughter and I could share. She was amazingly content the whole night, and enjoyed looking at everybody else's costumes!"
