The term CEL BLOC refers to a type of animation production process that was popularized in the late 1980s and early 1990s. The term is derived from the French phrase 'cellule BLOC, ' which translates to 'cell block.' This process involves the use of hand-drawn cels, or transparent sheets of celluloid, which are then painted with colors and placed over a background image. The resulting animation is then photographed and edited together to create a finished product. The term TOONS, which is the answer to the crossword puzzle, is a slang term for cartoons or animated films.
