Blue Coins might be gained by defeating certain enemy types or by pressing a Blue Coin Switch, which is a grey switch with a blue Star on it. If the player doesn't collect the blue coins generated by the switch in time, they will be gone forever. (or at least until the player restarts the level)
Other Types of Coins
There are two other types of coins:
- Regular Coins are worth one Coin and also refill 1 health when collected.
- Red Coins
- Worth 2 regular Coins and counts towards the 8 Red Coins challenge of the corresponding level.
