Play the "Library Memory" level. Get through the maze to reach an office room with two cubes on the table. Choose the red cube.
Easy "I DON'T LIKE AEROPLANE FOOD" Achievement
Avoid the patrolling stewardess hiding in the seats. Hide in a row that has broken lights or she will see you.
Easy "INDUCKTION" Achievement
You will start on an island at the beginning of the game. After learning how to progress, you will end up in the forest. Move forward until you find the axe. Use it to chop up the trees that are in your path. Ones that you can interact with have a blue aura. Also collect the gold duck when you find it. Continue and you will have to move some mine carts and chop more wood to progress. You will eventually go up a mountain and find a pedestal. Place the golden duck there and practice what you learned on the island to move to the next map. Continue forward, press the button, move across the bridge, and reach the briefing room. Watch the video, then look through door to the left to open a hallway. Use your running skills to proceed to the front door. Walk on up to the reception desk to find a blue duck. Approach it and a hand icon will appear. Interact with it repeatedly to advance through the pages.
Easy "THE FINAL COUNTDOWN" Achievement
Complete the true final Boss section with at least 31 seconds on the clock.
Easy "THE VIRUS, THE GLITCH & THE WARDROBE" Achievement
Play the "Childhood Memory" level. Once in the mirror universe, you will find two dollhouses sitting beside each other in front of you. The dollhouse on the left has stairs. Climb the stairs to reach the third floor. Look towards the other dollhouse. Make a running jump across to the other dollhouse's third floor (on the PC version, press [Shift] + W to run, then [Space] to jump). If a new scene does not start, turn around and move towards the wardrobe near the bed.
Easy "UNLUCKY DUCKLING" Achievement
You will eventually reach a point at the Fairground level where you will have the choice to go left or right. Go to the right until "UNLUCKY DUCKLING" is earned.
Easy "WELSH WIZARD" Achievement
Play through the game as usual until reaching the last level. Then, change the language to Welsh and complete the final level, including defeating the final Boss.
Easy "WHALES INTERACTIVE" Achievement
Play the "Beach Memory" level. Solve the puzzle on the beach and you will get in the water. Remain there instead of moving towards the pillar of light to find the exit. Eventually you will see at least one whale swimming around. You will not be able to catch it. Instead, find the whale that is simply floating in the water. Swim over to it to earn "WHALES INTERACTIVE".
