Mario & Luigi: Partners in Time Playthrough Part 8 (Thwomp Volcano!)
In this video, we go through Thwomp Volcano and come face to face with a scientist who is researching the area! He seems awfully familiar... anyways, afterwards, we battle Mrs. Thwomp, who is upset that her husband is sad. That's a fair enough reason, I'd suppose.
On a side-note, I feel like I'm playing this game WAY better in this Playthrough. I hope that I actually did improve.
