In "Ghostbusters" (1984), what form does the Destructor have?

The character as seen in the movie was created by Linda Frobos[6] by using miniatures and optical compositing with Bill Bryan himself in a latex suit. The suit was made of two layers, an outer flammable layer and inner fire-proof layer. Some of the finished movie's most noticeable errors appear in the Stay-Puft scenes: he is seen with and without his bow tie, while in other scenes the optical rendering was so poor that he passes through a church rather than crushing it. Also, the blue portion of his sailor suit is worn backwards.

The face of Stay-Puft was puppeteered by Terri Hardin. She used remote controls while laying down below the miniature street on the set as Bill Bryan walked around for his scene.
