Elmo Says BOO! is a 1997 Sesame Street direct-to-video compilation celebrating Halloween. Elmo visits the Count's castle to tell him funny scary jokes. Classic Sesame Street segments are separated with new joke segments set in the castle's exterior, featuring one Sesame Street character and a child, and interior, featuring the Count, Elmo, and some combination of the Bats, the Skeleton, a painting of the "Groana Lisa," a suit of armor and the Count's pipe organ.
