Through save file editing, it is possible to give Peppino transparent clothes. If the player forces the game to close when playing WAR for the first time, such as by pressing Alt + F4, this is not counted as a loss and the level can be retried to unlock the War Camo outfit.

There are 41 clothes in total. The game only lists the amount of them unlocked, but the unlock methods are never mentioned until they are unlocked. Clothes are also global unlocks, meaning that they become available on all save files after being unlocked once, but as such won't affect the Tower Status.
