Blue Spring

Blue Springs are objects that appear in Mario vs. Donkey Kong 2: March of the Minis and Mario vs. Donkey Kong: Minis March Again!, as a counterpart to Yellow Springs. They are blue-colored springs with a rounded top.

In Mario vs. Donkey Kong 2: March of the Minis, they are introduced in Room 2-1 of Tropical Island. If a Mini jumps onto a Blue Spring, the Mini is launched forwards in an arc, allowing it to reach ledges above and in front of it. Blue Springs can be affected by gravity and moved by conveyor belts. In Mario vs. Donkey Kong: Minis March Again!, Blue Springs are introduced in Room 4-2 of Jungle Rumble. They function identically to the previous game; however, a Mini will automatically jump on a Blue Spring upon reaching it. Box Springs containing a Blue Spring are also introduced in Room 4-2.

In Mario vs. Donkey Kong: Mini-Land Mayhem!, Mario vs. Donkey Kong: Tipping Stars, and Mini Mario & Friends: amiibo Challenge, similar springs known as Long Springs appear.
