"Happiny, the Playhouse Pokémon. It carefully carries a round, white rock that it thinks is an egg. It's bothered by how curly its hair looks." – Pokédex entry for Happiny.
"Ririka-chan, do you have a thing for Eggs or something?" Kanade asked her friend. "Not only is your first Pokémon a Happiny, but you also get to take care of Eggs every day at your part-time job at the Day Care. On top of that, your favourite food is Oeufs à la neige, a dessert mainly made from Eggs! How crazy can you get about them?"
"What are you implying, Kanade-chan?" Ririka teased back, causing Kanade to get flustered. "Is there anything wrong with that? If not, then there's no reason to question me about my interests. Besides, I'm the one who's given all of you Eggs from the Day Care to look after once they hatch into Pokémon, so I'd suggest not making another sound if you still want to keep them."
"Fine, I rest my case." Kanade admitted, slightly miffed that Ririka had poked a hole in her theory. "Although, it seems a Happiny is the perfect Pokémon for you. With how you both like Eggs and have curly hair, I can't think of any other Pokémon you could want!"
