In order to shoot, you need the pea-shooter from the starting room; to honk you need the horn from the haunted house behind the secret passage in the museum. Both items can be used from either of Jack’s two pockets, but if both are present, only the one in pocket 1 takes effect.

While on floor or street level, up means walking towards the back of the scene, and in order to jump both up and fire must be pressed. When standing on furniture, however, up or fire alone both makes Jack jump. It is therefore not possible to shoot or honk there, but that would never be useful either. The two secret passages are entirely in the “furniture” mode, meaning that you cannot shoot in these locations.

Being in contact with any moving sprite, some stationary ones, or hot surfaces gives Jack (nappy) rash. Five seconds of contact requires a nappy change, and the fifth change spells the end of the game. There is no way to reduce the rash or gain extra changes (lives) in the game.

Map

The fifty screens in this game are connected in a few different ways. All left or right-leading doors or streets are two-way connections which Jack can simply walk through. The three streets are also circular, so that going in one direction takes you back to where you started after a number of screens. Alleyways on the other hand are one-way and take you to the next street simply by walking into them; but in conjunction with the streets, these too form a loop allowing you to eventually get back to where you came from. Doors in the middle of screens can be of both types, but must be activated by the Enter key. Some are one-way, taking you to another room or out onto a street, while others are paired, taking you from the street into a building and back to the same street. Both the entrances to and the exits from the two secret passages are one-way. The entrances work like alleyways and are entered by moving up into them, while the exits work like doors and require the use of the Enter key. When exiting these, you are dropped into the connecting room from the upper left.

Pranks

Dropping any of the twenty-two items while standing on anything above the floor breaks the item, which yields 1 % naughtiness. Some of the items have no other purpose than this as far as I can tell; the others must be used for their unique purpose first, which normally gives 5 %. As the bomb and the clay both are destroyed when used, the points for breaking these are awarded when they are used. The pea-shooter can be used to shoot any character, and the first twelve times this gives 1 %. All these actions will annoy one of the characters on the screen, making them chase Jack until he leaves the location.

In the two inner rooms of the haunted house and the graveyard outside it, there are ghosts that chase Jack from the outset. As these can only be exorcised by a hit from the pea-shooter, it is necessary to visit the haunted house twice carrying the pea-shooter in one pocket in order to collect both items there.

The key is not itself used for any prank, but gives access to the secret passages leading to the haunted house and to the top of the wardrobe in the master bedroom, where the credit card is placed in order to be out of Jack’s reach.
