Or Pearl saying she learned this when she was "only" a few thousand years old, why would it have taken that long if she had been made for fighting purposes...
Also for some reason it didn't hit me until I saw Steven and Connie hanging out up there, but why is there a warp pad to the hand of the statue in the first place...
I can think of a few things, but it all depends on the origin of the statue and if it had a purpose other than showing there's fancy magic stuff nearby.
Also in one shot Amethyst had old outfit on XD
