Mario & Luigi: Superstar Saga Tips

Bottom Dweller Coins
To do this, you must aquire the Hammer abilities,
Mushrooms, and great reflexes. First, use Luigi
to hammer Mario into tiny Mario. Next, slect High Jump for Luigi. Press B, then press A.
You'll see Mario hitting Luigi's trousers and getting coins! But every time you hit Luigi's bottom, he takes damage. So heal him with a mushroom and then keep on doing this code for
coins! (This code cannot knock out Luigi on the overworld.)
