Home Alone/Jewelry Wing
Grab the watch off the dresser and open it to find a slingshot. Go left and check both sides of the desk to find a slice of pizza and a bag of money. Leave the room and take the slingshot and vase object on the shelf. Go to the left to find a burglar dressed in black. He won't move unless prompted, so don't touch him and he won't bother you. There's a banana peel on the shelf next to the burglar. Jump up and knock it off. When it's on the floor, open the cabinet to reveal a piece of jewelry. The burglar will rush after it and, in his haste, slip on the banana peel and fall off the page. Grab the watch and head back to the right.
In this screen, a burglar will walk under a trophy. Jump on the chair in front of you and knock the bowling ball above you off the shelf. The tremor will cause the trophy to fall on the burglar's head and knock him off the screen. Grab the trophy and continue right. Open the bottom cabinet to find a watch. Pick it up to make 6 valuables you are carrying. There is a conveniently placed laundry chute nearby, so use it to unload the valuables you are carrying. When your hands are empty, continue right.
Here, there is a burglar standing guard in front of a cabinet. If you open the cabinet while he's standing there, he will run over to the piece of jewelry that pops out, grab it, and run off with it. Make sure your water pistol is equipped, then fire at him a couple of times until he doubles over. As soon as he is assuming the position, open the cabinet and jump over him to get it. The door here leads to a bathroom. There's a piece of pizza in the shower head and a necklace behind the mirror. In the next screen, there's a watch in the trash can. If you stand on top of the toilet lid before using it, you will launch up into the ceiling and come down with a whole pizza.
Back in the hallway, go to the right. Jump on the chair then onto the drawers. Use the shelves as a staircase and jump off the top one into the next screen to land on top of a bookshelf. A pizza will pop out near the top, so drop down and grab it if you need some points. In the next screen, grab the vase, then drop down when the burglar is on the far side and go through the door. There's a necklace on the bed and a pizza under the pillow. This is probably the max you can hold, so go back to the laundry chute and unload before you continue. Use the chair to jump over the burglar or, if just shoot him if you're feeling particularly malicious. Back in the bedroom, there's a watch and a pizza in the dresser to the left and a bag of money on top of the closet to the right. To get to it, stand on the chair, open the drawer, and jump on it before it closes. Use the drawer as a ledge to reach the bag of money. When you've gotten it, head back to the hall.
Jump up the shelves and back to the top of the trophy cabinet. When the burglar gets near, run and jump over his head to get a 1-Up and continue to the right and down the stairs. The bowl of cereal painting has money hidden behind it if you jump on the correct stair. Under the stairs, you will see a locked door. It is inaccessible at the moment, but remember where it is.
Go left and enter the next door you see. Run left quickly, as a muscly thief will begin waddling after you. Jump on the table to get the valuable then at the chandelier to get a pizza slice. Don't linger for too long because the muscly thief had the odd ability to make painful things fall from the ceiling. Run and jump over his head and run to the right. Open the drawers nearest the door to find a bag of money, then go back to the hallway before he can catch up to you.
The next screen has a bag of money and a slingshot if you know where to look (in the drawer, of course). That should be valuable #6. The next screen has a laundry chute you should take advantage of. There are also cars strewn on the ground here. Be sure to jump over them or you will take a hit. Jump over the cars and grab the watch what flies out of the picture. In the next room, a lanky man will chase you. Run back right and jump over the cars and watch as he slips on them and falls, completely missing the floor. That out of the way, run back left and into the door there.
There's a valuable on the couch and a slice of pizza under the cushions that you probably shouldn't be eating. To the left, you will find a necklace in the cabinet and a baseball behind the TV if you jump. If you go back to the right, you will find a piano and a burglar. Check the chair to find a pizza slice, then use it to jump onto the piano. Check the cityscape picture to find a valuable and make sure to catch it before it hits the ground. After that, go back to the hall.
The dresser here contains a vase. Go back to the laundry chute and drop off what you have while you still can, then come back and go farther left. Check the picture of an angry man for another valuable. Jump over the cars and go to the left. The picture of a bowl of cereal here contains a necklace. Inside the room here, open the fridge to reveal a watch. Unfortunately, it is out of reach. Keep jumping at the end of the table until you can reach it. On the right side, you'll find a pizza in the over (finally something that makes sense) and a watch on the table. Once you've snagged these, go back to the hall and go left.
When you enter this screen, you'll see a lanky guy walking towards you. Quickly run to the table and take the vase, but don't open the drawer. Lure the lanky guy back to the cars trap under the angry man portrait. When he has fallen off the screen, go back and open the drawer to find a whole pizza. This is the last thing you'll find on this level unless you want to brave burly-man in the first room here. Run back to the right, remembering to jump over the cars strewn around. Dump off whatever valuables you have in the laundry chute when you pass it, then run until you get to the stairs. Now that you have all the valuables you need, there's a key here to access the basement. Grab it and go through the door here. Somehow you lock yourself inside a door that is padlocked on the outside. Oh well, there's only one way out now...
 The Basement
The basement is fairly straightforward- get to the other side without touching the bad guys. The first room's easy, just jump over them. The second room can be tricky. When you jump, they scatter so you can get through. Jump once to make them scatter, then jump over the first and run under the second. From here, do the same thing: Jump, then hurdle the first and flit past the second. In the third room, they're moving, but pretty slowly and predictably. Simply jump into the gaps they create. The fourth room combines the two, but since you have to jump anyway to get over the first one, it works out pretty well. Jump over the first, then jump through the vertically-moving ones while they're split. Jump the last one and you're off to face the boss of this level.
The first boss is fairly easy. All he really does is wander back and forth. Sometimes, he moves faster one direction or the other, but it doesn't change much. The depressed block in the center of the wall will cause a brick to be dropped if you touch it. The goal here is to drop a brick onto the giant ant. After you've done this 3 or 4 times, he'll keel over and you'll be free to seal up the valuables.
