Professor E. Gadd's Lab

Professor Elvin Gadd's Lab is the lab where Professor Elvin Gadd lives. The lab used to be tiny and used to be in Thwomp Mountain (as seen in Mario & Luigi: Partners in Time) however after the volcano exploded and destroyed his lab, he moved to a newer and better one in Boo Woods.

The lab's first apperance was in Luigi's Mansion. It had a Gallery where E. Gadd had pictures of ghosts but the ghosts all escaped into Luigi's Mansion.

E. Gadd also has a garage as seen in Mario Party 6.
