A Lady will say "This dress is comfy and easy to wear...", referencing Youngster Ben from Route 3 in Kanto, who said, "Hi! I like shorts! They're comfy and easy to wear!"
A female Swimmer will say "When I float between the waves like this, I'm like a mermaid. Now that I think of it, there was a tomboyish-mermaid Gym Leader in Kanto." This is a clear reference to Misty.
After entering the Hall of Fame, when the player stands behind the face board, an NPC will come and take a photo with the player, allowing them to earn the Face Board Memorial Medal.
