Malodorous Fibbian

The Malodorous Fibbian is an item in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. It is a toxic frog that was created by the Best Fitness Friends, who combined the frog's breath with Skeletone Formula:D to turn it into Malatone Formula:X and then feeds it to Morton, who then becomes against Bowser Jr. and his minions, thus throwing them right onto the ocean of Plack Beach.
