This is the 7th in the Wizard of Oz (There's no place like home) series. I grew up in this area and enjoyed being "home" to place these caches.
When Dorothy and her friends are in the Haunted Forest, the Lion has a spray pump with "Witch Remover" printed on it. In the next shot, it's gone. The reason is because there is a deleted scene in which the lion says that "the Witch Remover doesn't work but it's wonderful for threatening with". Disgusted, the Scarecrow takes the spray pump and throws it away. There is a close shot in which the spray pump hits the ground and vanishes.
*****The cache you seek is a small plastic container hidden inside the Haunted Forest. Beware, you never know when you might run into the witch who is after you. You do need to access this cache through the cemetery, so please always be respectful.
