Mario & Luigi: Partners in Time Nintendo DS Secrets

Infinite number of coins in Thwomp Volcano Inside

Inside the Thwomp Volcano, there are two tall rooms where you must use the Baby Spin move to fly down while gathering coins. Grab all the coins you can get, then switch to adult Mario and Luigi to go into the previous room and use the warp pipe to bring back the babies. Use the Baby Spin move again in the next room - all the coins will still be there, allowing you to do this numerous times to gain as much coins as you want.
