Its her classmate Pearls birthday, and the Rays are going to perform at her exclusive party. Troublemaker Pearl has invited just about everyone-- everyone, that is, except Shelly! Shelly urges Echo to go anyway, but Echo doesn't want to leave her friend out of the exciting celebration so Shelly hatches a plan to make sure Echo sees her favorite group. And when the Rays do come to town (amidst plenty of under-the-sea, boy band drama), Echo returns the favor so that Shelly is included in the festivities in the most unexpected of ways!"@en . .
