Wishing fork

Boober returning the Wishing Fork to the Trash Heap so she may eat her dinner.

A Wishing Fork was bestowed upon Boober by the Trash Heap in the book Boober Fraggle's Giant Wish. Stored among her tin cans and orange rinds, Marjory instructs Boober that whatever you wish for while holding the fork will come true, but if you want to unwish a wish, it must be done by sundown, for after that the wish sticks forever. She also tells Boober she needs the fork back at sundown so she can use it to eat her dinner.

Boober uses the fork to become the size of a Gorg, facing off with Junior Gorg. Gobo sits on the fork and accidentally gets a wish as well, before it is returned to the Trash Heap.
