Grandpa Rose is (or was, as it is unknown if he is still living) a mentioned but never-seen character in All Hail King Julien. He is known for being Clover's and Crimson's grandfather. He was also Grandma Rose's husband. Not much is known about him, other than that he almost married a lemur named Maxine instead of Grandma Rose. In order to marry him, Grandma Rose ate Maxine. He was mentioned in the episode The End is Near.
- Much like Clover's parents, Grandpa Rose was never seen, though he was named in The End is Near.
- As evidenced by Clover’s grandparents and Clover herself, plant and flower names seem to run in the family.
