Memories Guide
Bubblegum
Appearance: A wriggling piece of chewed-up bubblegum.
Location: Found in the Memory Room.
Begin the tutorial of the game, and follow the directions on screen. Walk to the end of the room and interact with the door, then return to the Memory Room. The memory will be present just below where you spawn, walk over it to obtain it.
Rose
Appearance: A red rose swaying from side to side.
Location: Found in First Steps.
Exit the Memory Room through the door at the bottom, then climb the stairs and enter the white doorway to enter First Steps. Heading slightly southeast will take you to a black bunny, where the memory can be found just below it.
Umbrella
Appearance: A purple and red striped umbrella with a red handle.
Location: Found in Rainforest Road.
From First Steps, head to the Black Waters by either diving off the cliff or going through the secret doorway directly right of the cliff (once unlocked). Move to the right until the area's monochrome signs transition into colorful red and green ones, which indicates that you have entered Rainforest Road. Continue down the road until you see a gap in the fencing directly below you, then head through it. Move to the left until you find a small clearing beyond the fence, then head south. Take the eastern path, then head south once more through the path marked by three signs stacked vertically. Once you've reached another road, go right to find a tree that appears to block you from going any further. You can simply go behind it, however, and loop around the fence to obtain the Umbrella that seemed just out of reach.
Snowglobe
Appearance: A snowglobe featuring a miniature brown house with a red roof depicted inside.
Location: Pink Snowscape
Follow the instruction in the Umbrella guide to reach the Rainforest Road. After going through the fence, take a right until you hit a dead end. Next, go south (ignoring the thin path through the trees), east, and south again and enter the igloo with a blue sign in front of it. You should now be in the Pink Snowscape, and heading directly north from the igloo will take you to the Snowglobe, which can be found resting on a pile of snow. Interact with it to obtain it.
Beach Ball
Appearance: A white and blue striped beach ball.
Location: Found in Red Sands B.
Once you arrive in the Black Waters, go left and enter the grey tunnel on the far side of the map to reach the Rusty Compund. Head slightly west, then south until you see another tunnel entrance enclosed in a circle of buildings. Enter the building from the side, then cross the room inside. You should now be in the Desert Settlement within Red Sands B. Go north past the building directly east of the building you entered the area from, and enter the doorway of the building you just approached. Go down the staircase on your left, then traverse the underground passage and climb the staircase on the far right. Exit the building and head directly left, entering the bottom house. After going inside, interact with the girl throwing the ball against the wall and she will disappear with a whimper. This leads to the Beach Ball bouncing across the floor, which can now be obtained.
Coins Guide
The coins found throughout the dream world serve almost no purpose as currency, but are instead the key to unlocking some of the game's endings.
