When you are out on your journey with Pikachu, you can also collect items for your bedroom, but only certain items. When you first start out, your bedroom is pretty much empty. Below are some items you and Pikachu should gather for your room decoration, and the items' whereabouts. Words in red are words to say to Pikachu, green are the Professor's words, and italics are my comments. You should be able to get the items in any order, so the items are listed in alphabetical order. There are a total of 23 decorations.

banana - A tropical fruit "Be sure to throw the peel away." You'll find the banana peel is worth nothing, and you'll find it at the Pinata Party too, and if Pikachu steps on it, it will get mad. The banana itself is located at Cobalt. Just pluck it off the trees. Pikachu focuses on the banana when you give it to it. In the bedroom, it should be located left of the door.

bird feather - A feather from a Pokemon "This light feather should fly pretty well." Pikachu will throw this when you let it hold it. You can't find this feather anywhere, but if you're lucky, Pikachu may find it for you, usually in Ochre or Springleaf. When you're in your room, you'll find this feather sitting on the desk.

blue marble - A blue ball of glass "I used to play with marbles, too, when I was a kid." Sometimes when Butterfree are hovering about some areas, they'll drop boxes containing marbles. Pikachu must use thundershock to break the boxes. Also, the blue marble can be obtained from Squirtle if you bring back 3-4 Poliwag in Olivine of the Play Days level. These marbles are also found at the Pinata Party when the pinata is broken. This will be in the left shelf at home.

bolt - An item used to fasten things "That's just junk." You can find this yourself in Ochre of the Play Days level in a hidden cave full of magnets and stuff. Sometimes Pikachu will find it. The bolt will be sitting in the right shelf of the bedroom.

chocolate coin - A coin made of chocolate "Don't mistake it for a gold coin!" You'll earn this coin in the Pinata Party, and you'll also find it in the chests of Cobalt. The chocolate coin will be sitting in the right shelf when you get hold of it in your bedroom.

copper coin - A coin made of copper "It's worth about 10 PikaPoints." This coin is found in Cobalt chests. It sits with the chocolate coin on the right shelf in your bedroom.

daisy - A small, white flower "It doesn't stand out much, but it's a cute flower." This can be found all over Viridian in the Daring Days level. It will sit in the flower pot to the left of the sliding door.

lily - A large, white flower "I think this one smells nice, but I am not sure." You'll find lilies scattered throughout all the Springleaf areas. It should sit on the window sill to the right of your bed.

magnet - A magnetic piece of metal "It's a pretty cool shape, but it's just junk." You can find the magnet in Ochre of the Play Days level sitting with a couple bolts. The cave it sits in is hidden, and I can't really pinpoint the area for you. The magnet sits in the right shelf of your bedroom.

marble - A ball of glass "I used to play with marbles, too, when I was a kid." This marble... Pikachu finds it for you. In the bedroom you'll find it sitting in the right shelf with your coins and Magnemite pieces.

petunia - A white flower "What an elegant looking flower." Okay, in my picture it's purple, but really, it looks more purple that white to me. You'll find petunias all over Viridian, and you can collect them in the Daring Days level. Petunias will be in the left flower pot next to the sliding door.

pirate flag - Symbol of a pirate ship "That's a prize from the pinata party." You'll earn this from Venusaur when Pikachu breaks the pinata. It will be hung up on the wall between your shelves.

pirate sword - A sword once used by pirates "That's from the pirates' plunder on Cobalt Island." The sword should be found on Cobalt and I believe you can also win it at the Pinata Party. This sword sits on the right side of the shelf above your bed.

red marble - A red ball of glass. "I used to play with marbles, too, when I was a kid." Sometimes when Butterfree are hovering about some areas, they'll drop boxes containing marbles. Pikachu must use thundershock to break the boxes. These marbles are also found at the Pinata Party when the pinata is broken. The red marble will be in the left shelf at home.

ruby - A hard red gem "You can see through it. Isn't it beautiful?" You'll receive the 5000 PikaPoint ruby when you successfully babysit the Caterpie in either Viridian areas. The ruby sits with your gems and marbles in the left shelf of the room.

sapphire - A hard, clear blue gem "That's an amazing color of blue." You can get the sapphire by finding all the Poliwag in Olivine on the Daring Days level. Make sure you get them to Poliwhirl, though! The sapphire is with all the other gems and marbles on the left shelf in the bedroom.

silver coin - A coin made of silver "It's worth about 100 PikaPoints." You'll get the silver coin from Squirtle when you find all the lost Poliwag in the Play Days level. You can also find it at the Pinata Party and Cobalt Island areas. The silver coin is on the right shelf in the bedroom.

Telescope - An item used to view the night sky. You can't touch this item at all. When you're very good with Pikachu, Professor Oak will send Pikachu on an errand to buy a Telescope for about 20000 PikaPoints (hope you know how to save up PikaPoints fast!) and when you receive it view the night sky with it. After seeing the end credits, you'll find the Telescope sitting on the book shelf.

tissue - Thin, light paper "Be sure to clean it up after scattering it about." This is already in your room. Sometimes Pikachu will run over to the tissue box and pull tissue out one by one. The tissue box is to the left of the door next to the banana.

topaz - A delicate yellow gem "It's a very valuable gem that's really hard to come by." This is very difficult to get. You have to head over to the Cobalt area in the Daring Days level and head for the fort-like structure on the rocks. There's a huge chest at the top and you need Pikachu to open it. The topaz sits on the left shelf.

toy sword - A toy sword made of wood "En guarde! I used to play with toy swords when I was little." You can win the toy sword at the Pinata Party and find it in chests at Cobalt in the Daring Days level. The toy sword sits on top of the shelf above your bed.

trumpet - A loud, brass instrument "This makes a pretty loud noise." The alternative to the harmonica, the trumpet can be bought as a souvenir from Abra's Shop in Springleaf of the Play Days level. Tell Pikachu to play it. This item sits between the bed and the boom box.

yellow marble - A yellow ball of glass "I used to play with marbles, too, when I was a kid." Sometimes when Butterfree are hovering about some areas, they'll drop boxes containing marbles. Pikachu must use thundershock to break the boxes. These marbles are also found at the Pinata Party when the pinata is broken. The yellow marble will be in the left shelf at home.
