My only complaint with this episode is that it made Dawn look really weak.
She had to hide from Team Rocket? Wouldn't Piplup, Ambipom, Buneary, or Pachirisu be good enough to defeat them?
And Aggron, why couldn't Piplup or Ambipom beat it? At least Piplup and Ambipom(focus punch) would have a type advantage rather than a disadvantage like Mamoswine
