Frookie is the love of Grizelda's life, being carried around by her wherever she goes. Frookie seems to have a rather simple personality, easily getting into mischief (such as being duplicated four times by the Flowerus Magnificus in "Frookie Sitting"). Frookie loves to lick and pounce on Bartleby, to his disliking.
Frookie is a small white dog with magenta eyes, a red collar holding a dog tag with the letter F on it, and a matching crystal crown with a red jewel in it like Grizelda's.
Despite Bartleby's aggravation, and at times jealousy towards Frookie, he loves pouncing on him and licking him until Bartleby gets him off of him. Bartleby tends to point out Frookie's traits such as drooling.
