One day two curious explorers were taking a ride on a mine cart. They wanted to know where it lead so they decided to walk along the track. Eventually they came to a room that was unknown to penguins. The explorers looked behind them and saw a lump of snow. They grabbed snow shovels and dug it out. When they finished, they saw a big, red shack now known as the Mine Shack.
On April 17, 2010, construction began in the Mine Shack to make it look nicer and turn it into a Recycling Plant. By the Earth Day 2010 party, the Recycling Plant was completed. This room housed Gary's newest invention, the Recycletron 3000. Penguins then gathered recyclable objects for the Recycletron 3000, which turned the items into Lamps, Anvils, Buoys, or Life Rings. It actually grows, from a little tree with a few twigs to a huge tree with branches. There were rumors that there would be a different entrance to the Recycling Plant if the tree grew too big.
Up until 2010, the Mine Shack could only be accessed through the map. But in 2011, a new route was added between the Forest and the Mine Shack, creating a shortcut.
After the release of the Quest for the Golden Puffle, it was renovated with stairs leading down to it, and the track with mine cart was removed.
In April 2010, a garden was added to the room. If you threw snowballs into the big watering can, a sprinkler would turn on and water the plants. They would then be harvested and stored in the shed. It had been proven that the tree to the left can grow. As of July 11, 2013, the garden is at the bottom of the room, and can no longer be watered.
After the Earth Day 2010, a tree was planted at the top left side of the Mine Shack. At first it was a little tree or 6 branches of 4. Then it slowly became larger and larger until full size, which is bigger than the Mine Shack itself. If the tree grows too large, there would probably be a different way to go to the Recycling Plant. Over time, the Community Tree would get bigger. It has grown 3 times since it was planted. After its renovation, the community tree moved to the left of the School.
During the 2007 Halloween Party, the Mine Shack was replaced with a large, abandoned house.
During the April Fools' Party 2008, the Mine Shack looked like a connect the dots paper but when it was finished, a crayon pin appears on the side and then Mine Shack looked normal.
During the 2008 and 2009Medieval Parties, the Mine Shack was a cave entrance and there were stacks of gold on the mine carts. There was also three signs near the cave entrance, one reading "No Knights" another reading "Princesses Welcome" and the third read "Beware of the Dragon."
During both Water Parties (2007 and 2008) there was a giant bucket that filled with water and tipped over, spilling the water.
As stated in the Penguin Times, The Mine Shack is needing a cleanup as of the Earth Day 2010.
As of June 15, 2010, there's a statue of Herbert P. Bear, which can also be seen in Herbert's Revenge. This was added because of the last mission in the DS game: agents needed to find a way to stop the geyser at the mine.
