Interestingly enough, Ginger's harrowing. She and the Girl in Red Wolf playfully chase each other around the field of flowers, and then fall to the ground laughing.
Robin jumping on her wolf's back and getting a piggyback ride from it is Awww! worthy.
Robin in general is a pretty cute little girl. If you explore the woods with her, you can witness her swing on a swing, skip up to items (as opposed to her sisters, who simply walk up to them), and play pretend with a shopping cart.
Robin: I'm a kid, I'm a kid, I'm a little kid! And I play, and I play in my little way! Buy me now at discount prices!
There's also Robin's reaction to picking flowers, a rare reference to the other sisters.
Robin: A flower for Rose and a flower for Carmen, a flower for Scarlet and a flower for grandma…
If you let the Girl in White lead you back to the path, once you're there, she will hug you tightly before disappearing back into the forest.
Ruby actually giggles when The Girl in White plays with her!
Ruby's fond giggle also shows up if she goes to the Bunker after Ginger has spraypainted a smirking face on it. Even though what Ruby paints is very different, she likes her sister's logo.
If you have the girls stay on the path instead of meeting their wolves, they each go through a normal version of Grandma's house, ending with them entering Grandma's room and laying down next to her on the bed. Yes, even Ruby, Carmen, and Scarlet.
