Adrift and Alone

Adrift and Alone is the last level in Plack Beach for the story in the Bowser Jr.'s Journey mode in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey.

Overview
Bowser Jr. and Kamek find Iggy on Plack Beach, although he does not appear to remember them and keeps speaking in slang sentances. Kuzzle then arrives, who thought Iggy was his grandson Charlie, and explains he found Iggy on the beach with amnesia. Bowser Jr. and Kamek proceed to fight Iggy, in order to give him the "Shock Therapy". Afterwards, Iggy regains his memories and his usual personality and rejoins the team, making Bowser Jr. and Kamek relieved. They then spot Kaley and Beef fly past, who were talking about Ludwig. Bowser Jr., Kamek and Iggy decide to follow them, while Kuzzle thinks Kaley is one of his grandchildren and rambles the names of them.
