Instructions
Select Mission 2 from the mission select menu to get the first of six snake coins. Put on the goggles once you get them in the mission, and then travel to the snow forts area. When you reach the snow forts, use the flare to melt the snow. You will then play a mini-game with the snake coin as the reward.
Select Mission 3 to get the second snake coin. Move to the river that flows near the base at the beginning of the level. You will see a fish jumping in and out of the water. Use the loop to grab the fish, and you will earn the coin.
Go to Mission 4. In the gift shop area of the level, you will see a machine with multiple prizes including a snake coin. Use "chirp" on the machine, and the coin will fall out.
Choose Mission 5 from the mission select screen. Go to the mine shaft area of the level, and you will see a large anvil. Select "pop" from the list of puffles, and he will lift the anvil for you. Underneath will be the fourth snake coin.
Select Mission 6 from the menu. Talk to the gift shop attendant in this level, and he will ask you to fix the safe. Choose "flare" to fix the safe, and then use the wrench in your inventory to open it. Inside will be the fifth snake coin.
Go to Mission 7 to get the final snake coin. Before you go up the ladder in this level, move into the corn to the left of it. You will find some water there, which you can freeze with "chill." Cross the newly created ice, and you will find the coin.
