Blue Coin Block

The Blue Coin Block, also called Blue Coin switch and Blue Switch (or blue Switch ), is an object found in Super Mario 64 and its remake Super Mario 64 DS.

When Mario finds a Blue Coin Block and Ground Pounds it, Blue Coins show up nearby. Mario has a short time to gather the Blue Coins, after which they disappear. The block cannot be reused. The amount of Blue Coins that appear varies with each course, ranging from two to ten or more; they are often necessary to obtain the 100-coin Power Star from the levels they appear in. During the time that Blue Coins appears on the screen, a timer can be heard, which ticks faster when the time is running out. Due to its role, it is comparable to the P Switch, except that it does not change coins into Brick Blocks and vice-versa.
