School Daze Part 1 & 2
Silverstream enrolls in Twilight Sparkle's newly opened School of Friendship as a student, having been brought to Ponyville by naval general Seaspray to represent the Hippogriffs. Initially, Silverstream is particularly excited to be at the school, but Twilight's strict adherence to the Equestria Education Assocation's guidelines cause the school courses to be dull and boring. When Silverstream cuts class with Sandbar, Smolder, Gallus, Yona, and Ocellus, the six hang out together and slowly become good friends. They later return to school for Friends and Family Day, but they accidentally ruin the event and cause damage to the school. Chancellor Neighsay of the EEA perceives their fun and games as an attack orchestrated by other non-pony creatures, and the offended tribe leaders pull their students out of school, including Silverstream.
Not wanting to say goodbye to each other after the school is closed, Silverstream and her new friends go into hiding at the Castle of the Two Sisters. The six have fun together at first, but they are eventually attacked by ferocious puckwudgies, prompting the Mane Six to save them. When Silverstream and her friends are asked to come back to school, they are reluctant to continue their boring lessons, but Twilight and the others assure them things will be better and more fun than before. After Twilight defies the authority of Chancellor Neighsay and reopens the School of Friendship, Seaspray allows Silverstream to re-enroll at the school, much to her extreme delight.
