Amy incorrectly calls the Manga as 'comic books'. in her quote, "I'm collecting the Pokémon bean bags and toys. I can't wait for the comic books!".
The Poké Ball on the chalkboard is misspelled as PokéBall. This is supposed to be two words, not one.
Amy mispronounce Pikachu's name, calling it calling it 'Pick-a-chu' when it is 'Peek-a-chu'.
