Grandmommers Whimsical is Queen Delightful's great-great-great grandmother and former ruler of Jollywood. She is first mentioned in "Sneezin' Season" and later makes an appearance in "Big Rock Candy Flim-Flam" by visiting Delightful. She was voiced by Debbie Reynolds, in her final acting role until her death in December 2016.
Grandmommers Whimisical wears a gray, light gray and white dress; and red lipstick. On her white, oversized hair is a crown with her cat riding along on it, much like Delightful's crown that's also used a perch for Squire Peckington.
Apparently, Grandmommers Whimsical shares Delightful's goofy traits. She even goes on a tizzy (her hat would light up and she imitates a siren), just like her great-great-great granddaughter.
In the show
Grandmmomers Whimsical occasionally stays at Delightful's castle as a guest, and usually arrives at precisely three minutes after midnight. But as she travels to her destination via the Sky Bucket around midnight, two Candy Sprites caused the destruction of a huge candy rock housed inside a giant outdoor cuckoo clock that is the source of time throughout Jollywood. Time froze, and Delightful, who's expecting Whimsical to arrive at 12:03, becomes extremely worried. With the help of The 7D, the dwarfs locate another candy rock and went with it to the cuckoo clock for replacement, while fending off the Candy Sprites. The 7D successfully installs the new candy rock, time resumes, and Whimsical is able to arrive at the castle at exactly three minutes after midnight.
