(summary of the short)  
At the CHS band room sunset and Sci twi work together to come up with a new song for the rainboom. But all of sudden both sunset and Sci twi geodes start to glow. First off they were wounding why sunset empathy magic wasn’t working or twilight telekinesis. They were a little confused at first but it all stop when they saw a bubble..both sunset and twilight were really confused. Was this a new magic that only they could do. As the geodes stop glowing two more bubbles then a couple more. Sunset and twilight know they had to get rid of them before the students or before principle Celestia see.
