- Queen Undine is referred as Sophia's grandmother in the original version, but in the Malaysian dubbing, Sophia refers her "makcik" (literally "Auntie") instead.
- Queen Undine's role is similar to King Triton from Disney's Little Mermaid. Both are strict to their daughter/granddaughter due to the lost their loved one (Triton's wife, Queen Athena. was killed in an accident by the human, Undine lost her husband, son, and daughter-in-law to Bulkin's invasion) and want what is the best for them.
