This achievement is missable and can only be done in Part 2. When tasked with reporting messes on the ship, you need to find all 8 possible messes. To do this, save your game before finding any, find five of them, and then reload the game to find the other three. Here is the list of the possible messes:
- Gullet stuck down the back of in the ship underwater
- The spilled potion on the deck
- The entire galley (go in kitchen and select the ingredients)
- Any grease spots in the hold (you need to create at least one with the mop and the grease at the beginning of Part 2)
- The greasy porthole in the hold
- The rat outside LeChuck's cabin
- The empty crates on the deck
- The chicken splat in the hold (you need to feed the chicken on the top right of hold with some chicken feed, leave the hold and come back. The splat will be underneath the chicken)
