This episode guest stars Pauline Rennie as Aunt Gertie. She is more known for some of her work on The Care Bears (1986) as Cozy Heart Penguin, Grams Bear, Treat Heart Pig and a couple of others. When Cyril's Bears are building the Dam (During the Song), you can see a Care Bear on the top Visible Level. However, we can't see if the symbol on the chest is Grams Bear or not.
