To pay off the ruby debt on the second chapter first work off around 101 rubies by hitting the energy blocks(talk to the whip holder at the other end to start)then go to the jail cell to the far left of this room(not the one with the keypad)and talk to the worker with the red clothes and pay him 1 rubie for the info. Then switch to Peach and then float to the other end of the gap where you started and enter the cell there and talk to the guy with red clothes and hell give you the code to the VIP section for 100 rubies then use Mario to flip into 3-D and go past the support beam and there should be a chest there and you should open (I think I cant remember) and youll get a Pixl named slim then go to the VIP room and enter the room with the code and work on the wheels for 10000 rubies then go back to the first cell and switch to 3-D and talk to the gut in the red in the corner of the cell and hell give you a long code(write it down)for 10000 rubies then go to the far left and switch to 3-D then hit the block and go up the ladder. Now use Slims power to pass the moving energy walls and get to the safe then enter the code and open the door. Youll get 1000000 rubies (your debt) then go back to Mimi and deposit the rubies. (you could have probably figured this out your self but I was bored when I typed this.)
