Bobbery in Your Party Early
Get Ms. Mowz before going to Keelhaul Key. Swap her with another partner, then open your inventory. Try to use an item on a character, and you’ll see Bobbery in the list replacing Ms. Mowz! (At this point in the game, Bobbery is next to join your party.) Use an item on Bobbery and it causes his name to flash, but any HP item will be wasted because Ms. Mowz will doesn’t get it. If Ms. Mowz is your current partner then the list is normal.
Sell your L Emblem or W Emblem badge while it is equipped. Your clothes will still be different from the badge until you leave the current screen.
