Neighbours Back From Hell

For this trophy, you're only required to complete each level with the minimum number of medals. If you're finding any of the pranks to be particularly difficult in their timing, chances are you can skip it and still meet the requirement. This season gets significantly more complicated, as you're out in the open and there are two people you have to avoid instead of one. Make sure you're either using :R2: to sneak, or walking in short bursts if someone is sleeping nearby, so as not to wake them, and pay attention to the green filter over their profile so you know when they're about to wake up. Below is a written walkthrough for each level, along with a video of each level.

Covert Advance

Grab the Shark Fin from the trash can on the left, and then head right. Grab a Reed behind the path and then head left again and downstairs. Grab the Seaweed from the far left, the Bucket and the Sawfish from the sign. Use the Reed on the crab hole and complete the mini-game for a Crab. When he heads upstairs, use the Crab on his cooler, interact with the rake and use the Seaweed to cover it. Head left and use the Shark Fin on the remote submarine, and then head upstairs. Use the Bucket on the eel tank, and head right once it's clear. Use the Bucket on the pond behind the bridge, and the Sawfish on the railing. Head left and wait for the level to end. 

The Cabin is Occupied

Head right and interact with the purse to get the Nylon Tights, and then take the Chili Sauce from the counter. Head upstairs and grab the Cannonball and the Oil Can, and use the Nylon Tights on the generator. Once the neighbour goes downstairs, head left and take the Wrench from the tool belt. Use the Oil Can on the level to the left of the toilet, and use the Chili Sauce on the toilet paper. Head right, and then downstairs, and wait for the neighbour to go back upstairs. Use the Cannonball on the melons, and then use the Wrench on the bike. Head to the right and wait for the level to end.

For Whom the Gong Sounds...

Interact with the arcade game and get the Bear. Head right and trade the kid the Bear for the Popper. Take a Brick from the pile and pick up the Bonsai Scissors. Go downstairs and pick up the Rice Bowl, and then head left and pick up the Umbrella Stand. Wait for the neighbour to move to the top right area, and then head upstairs. Use the Rice Bowl on the grease bowl, and then use the Umbrella Stand on the gong. Wait for him to go downstairs, and then head right, using the Popper on the hot dogs. Wait for him to move left, and then go downstairs and use the Rice Bowl on the vase, and the Bonsai Scissors on the necklace. Wait for him to go upstairs, and then head left, using the Brick on the karate demonstration. Wait for him to move right, go upstairs, use the Rice Bowl on the grease again, and then go back downstairs and use it on the rickshaw. Avoid the neighbour by walking clockwise until the level ends.

Ping-Pong Fucius

Wait for the chef to put his Glasses down, and then take them. Interact with the duck cage to get an Egg. Head right and get the Inner Tube from the crate, and then pickup the nearby Hammer and Nails. Go downstairs and use the Egg on the ping pong table, and then take the Rope from the anchor. Wait for the neighbour to get back from water-skiing, and when he goes upstairs, take the Bangers from the box and use the Hammer and Nails on his skis. Head right and upstairs and use the Bangers and the Glasses on the lion statue at the top right to get the Lion's Head. Make sure he's in the bottom left corner, and go back to the chef and use the Inner Tube on the basket of eels. Wait for the neighbour to move right, and then go downstairs and use the Lion's Head on the sand sculpture, and the Rope on the rockets. Now just avoid him until the level ends.

Every Shot A Hit

This level can be a bit of a pain, as you're now hiding from two people, and the timing on sneaking past sleeping people is very tight. Consider moving in short bursts rather than sneaking with :R2: and remember that it isn't a big deal if you're spotted, just get back to where you were and continue. 

Grab the Rubber Band from the sports bag and the Whoopie Cushion from the toy box. If you're quick enough, you can get upstairs and hide the Whoopie Cushion in the cushions and hide in the pipe before the neighbour arrives. By the time he goes downstairs, his mom will be asleep, but you won't have a lot of time. Sneak over and grab the Flea-infested Blanket and Furry Rabbit from the ground, and then head back right to where you were. Wait for her to wake up and fall back asleep to reset the timer, and then make your way to the vending machine on the wall. Get the Denture Adhesive and hurry downstairs before she wakes up again. Use the Rubber Band on the harpoon gun, and the Furry Rabbit on the box of toys at its base. Wait for him to head upstairs, and then use the Flea-infested Blanket on the dumbbell. Once he heads left, go upstairs and use the Denture Adhesive on the box of dynamite, and then hide until the level ends.

Mummy's Darling

Start by taking the Urchin, the Spring from in front of the green bike, and the Pedal from the red bike. Head left and pick up the Whisky next to the towel. Wait for the neighbour to move right, and for his mom to dive under the water. Go upstairs and use the Spring on the diving board, and then head back downstairs. Wait for her to get out of the pool and fall asleep in the chair, and then sneak upstairs and to the right. Give the Whisky to the bartender and take the Bucket. Wait for the mom to dive underwater again, and use the Bucket on the tap, and then head right. Pick up the Tongs from the barbecue, and then use the Bucket with the elephant. Go downstairs and use the Tongs on the crab hole. Use the Crab with the conch shell, and then take another Crab from the hole. Head left and use the Crab on the sand castle and the Urchin on the blanket. When she dives underwater again, go upstairs and use the Pedal with the awning pole on the far left, and then pick up the Spring and use it on the diving board again. Head downstairs and hide in the wicker bench until the level ends.
