The Moon gets sad when Oscar loses his friendship bracelet.
Tropes:
- Accidental Misnaming: According to the Sun, she and the Moon used to rise at the same time until she misspelled his name as 'Hoot' in a birthday card. This hurt the moon so much that he refused to rise alongside her anymore. She also claims that the owls never stop giving her grief over it.
- Friendship Trinket: The Moon considers the bracelet he gave Oscar to be one, and is upset when the latter loses it.
- Here We Go Again!: Played with. At the end, the Sun points out that Oscar has lost her bracelet, and it seems like she is upset, but she assures him that she doesn't actually care if he did lose it.
- Making a Splash: The Moon has control over the tides and water. When he leaves, so does the sea.
- The Power of Friendship: Oscar's song creates friendship bracelets for him and the Moon. Justified since friendship is what the Moon values most.
- Our Mermaids Are Different: The mermaids seen here are half narwhal, half fish.
