Mrs. Thwomp

Mrs. Thwomp is a female Thwomp in Mario & Luigi: Partners in Time. She is married to Mr. Thwomp and she is very easily angered. She lives in Thwomp Volcano. Unlike all other Thwomps, she is shaped like a boulder. She is also the first known female Thwomp - along with Female Chain-Chomps.

In the game, when Mario, Luigi, Baby Mario and Baby Luigi come to the volcano, it erupts. Thanks to E. Gadd's help, they were able to put the fire out. However, Mr. and Mrs. Thwomp waited each year for the volcano to erupt, but, when Mario and Luigi stopped the eruption, they became upset. As the brothers made their way to the summit, Mrs. Thwomp decided to take her frustrations out on them in a battle. During the battle, some Micro Goombas help her as a decoy when she shrinks.

After being defeated, Mrs. Thwomp got angrier, but her husband attempted to calm her down. Afterward, Mr. Thwomp offered to take the brothers into Thwomp Caverns of which they took him up on.

Mrs. Thwomp is not necessarily a villain, but her temper can be misleading.
