Pink Coins[1] are a new kind of coin added to Super Mario Maker through a software update released on March 9, 2016. It can be produced by shaking a coin when editing a level. They are similar in appearance to Red Coins, and share a similar sound effect when obtained as well. If Mario collects all the Pink Coins in the level, a key will appear, which can be used to unlock a locked door. A maximum of five Pink Coins can be placed in the main level, in addition to another maximum of five in the sub-level. All Pink Coins are part of the same collection and all go towards one key, even if two sets of coins are put into both the main and sub-level.
