Who knows!

"So what exactly did I unlock?" I ask Mella, still standing in the middle of the stairs.

Mella looks at me mischievously and in a sing-song teasing voice says, "Wouldn't you like to know? I can't tell yoooooou. HAHAHAHAHAHAHA!" It seems her manic side is coming out even more with this excitement. "Seriously though, if I tell you the effect is greatly diminished and trust me, you don't want to do that."

"Ok, fine. I guess I will have to figure it out myself. Will you tell me everytime I unlock some new hidden thing?"

"Nope! I mean I could but that wouldn't be fun. You need some surprises. Can we go upstairs now to play or do you want to go back in the kitchen to try to figure out the hidden surprise?" From the sounds it seems like Kelly is moving around like normal again.
