I thought that box was pointless, especially when the Mane 6 earned some bullshit keys for doing whatever reason not explained. By the season 4 finale, it made them go Dragonball Z on Tirek, cuz why not. After that, it sprouted out a hideous Crystal Empire castle ripoff instead of fixing Twilight's library that was infamously destroyed! Or even make it look like a tree that matches Ponyville and Twilight's library!
Why!? Is it because Twilight turned into an alicorn princess and the writers think princesses are supposed to live in castles? How stereotypical.
