Pinkie's such a musical character, so I used another My Little Pony song from G2 for her to sing to Rainbow. ^-^

To the ones who debate the songs origins: it is from My Little Pony Tales, the reboot AFTER the G1 show, My Little Pony 'n Friends (plus a few films) stopped. This makes it G2. The toy line is irrelevant to the TV shows because the shows are rebooted every decade, whereas the toys have their own set of remakes. The G1 toys were still out when this show aired, but were not related, just as the G3 toys they sell now aren't related to G4.
