Rocks and Secret Areas!

RR: Secret Area(Game): During invitations-have Penelope with you in the group. Turn off the light switch. Go all the way to the paw thingy and climb up. There is a game there. It is an unknown game, because when the light switch is on, there's no way to know that a game is there. And it is impossible to get to during the rescue of the rainbow, as you don't have enough ham-hams to get up to that point.
