Quoted By:
A lot of people forget that Erika is a Princess and has many servant maids.
She has a deep love for nature, and flower arrangements.
Shes often depicted as sleeping or doozing off.
Possibly a reference to sleeping beauty or other fairy tale princess stories related to sleeping. Or a simple nod to beauty sleep.
In the games usually each of her Pokemon know one sleep inducing move
She was an excellent choice as a trainer for 151, but Sabrina, Misty, and Lorelei should have been as well.
