Solgaleo and Lunala (the new sun and moon lengendaries): On the floor Riolu and Braixen: Do you wanna build a snowman (from frozen) Pansage: Three little birds Infernape: Part of me
Let me explain the second one. Riolu and Braixen were best friends when they met. But a few weeks later Riolu was killed by a Zoura. After Riolu died Braixen was confused why Riolu wouldn't meet him when she got up like always. The last lyrics of the song say that Braixen has found out that Riolu was dead. Trust me Braixen's backstory of when Riolu was killed is really heartbreaking. Scratch on Scratchers! Part 52 coming soon!
