I dunno about Lost Jungle, but in Mystic Mansion, it involves the switches. One of them will have rails at the top. You know how the other teams can use those rails to reach a higher area? Team rose doesn't have the pulley, but if you jump at the top of the curved rail, you can barely get up there (Though you'll have to thundershoot at the top to get rid of someone to get on.) HOWEVER, if you hit a switch past the goal, you won't be able to go back.
