This is Jeff Gurwood's Indymation, a.k.a. the entire temple sequence to Raiders of the Lost Ark done up entirely with action figures and art supplies. If I were animating the film's final scenes, I would make Gumby jump out of the Ark of the Convenant. That guy absolutely terrifies me. Also, I wonder if Indy's friend is a Doctor Octopus action figure.
