Get the Giga-carrot
From the Super Mario Wiki
Get the Giga-carrot is a level in Dimble Wood in the Bowser Jr.'s Journey mode of Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey.
The level has three battles. The first battle starts off with one Goomba, two Paragoombas, four Treevils, and a Fire Stalking Piranha Plant first officer and captain. The second battle contains one Goomba and two Paragoombas at the front, three Treevils and a Fire Stalking Piranha Plant in the middle, and a Fire Stalking Piranha Plant first officer and Treevil captain in the back. After the battle, Bowser Jr., Iggy, and Morton have finally found the Giga-carrot. Unfortunately, it was too heavy to carry, so Bowser Jr. took a big bite out of the carrot. Bowser Jr. asks Morton on where to go next, but Morton tells him that he doesn't know where to go next, along with Iggy. Iggy was sad that they couldn't ask the other Koopalings about the next ingredient's whereabouts. Bowser Jr. gets mad hearing him say that and says to him that he never wanted the other Koopalings at his side. Kamek, in search of Bowser, finds Bowser Jr. and the two Koopalings, and asks where everyone else went. Kamek joins the group as a minion after this.
