Blue Spring

Blue Springs are one of the obstacles that the Mini-Marios face during the events of the Nintendo DS game Mario vs. Donkey Kong 2: March of the Minis. These objects first appeared in Tropical Island Room 2-1, and so on in later levels of the game. Their appearance is simply a blue-colored spring which has a rounded top on it.

When a Mini-Mario uses them, the player has to draw the stylus up near to the spring. When the toy jumps on the spring, the Mini-Mario will jump high and also accelerate forward depending on the direction the toy is about to make. Using them is a good way to get onto ledges. These objects can't be moved, but also not fixed onto the floor.

A similar object introduced in the game is a Yellow Spring.
