Ron Weasley makes a reference to Pokemon

[Petzbreeder]

In Harry Potter and the Philosopher's stone, Ron casts this spell on his rat Scabbers:

Sunshine daisies, butter mellow
Turn this stupid fat rat yellow



Does this remind you of anything?
I have read hundreds of Pokemon and Harry Potter websites, not a single one of them has pointed out the reference!

The book was released in June 97, the pokemon anime didn't even reach America till 98. If the line is only in the film? Maybe I guess.

[Captain Jigglypuff]

It was in the book as well. The part that was only in the movie in the scene was Hermionne fixing Harry's glasses.
