Li'l Miss Marshmallow

Li'l Miss Marshmallow (Japanese: マシュマロちゃん Marshmallow-chan) is an optional boss in Mother 3. She is Porky's robot maid and can be found in a room in Thunder Tower. When Lucas talks to her, she only states that the room belongs to "King P". However, when Lucas tries to take Porky's yo-yo, she becomes furious and attacks the party.

In battle, Ms. Marshmallow has two forms: Normal Form, where she looks like a simple robot maid, and the "ultra-ticked off" mode, where she is armed with drills and scissors.

After being defeated, Lucas and his friends can access the Friend Yo-Yo, which can only be found here.
