Buttons (Test Subject series)

Buttons are interactive objects in Test Subject Blue. Buttons have a purple metal top and a green button in the middle of the purple metal. Buttons face horizontally, so they are placed on walls. Buttons make a fair amount of appearances in Test Subject Blue. To activate a Button, it has to be shot with a Blue Enzyme Bullet from Blue's Proton Cannon.

When the Button is shot, it will deactivate all Green Teleporters in the level for a short time. Although it deactivates all of them, the ends of the Teleporters can still be seen. When the Teleporters are down, the Green Button on the Button will go down, and when the Teleporters come up, the Green Button will come up.

Orange Enzyme Bullets and Orange Enzymes will not trigger the Buttons, despite the Orange Enzyme Bullets being quite similar to Blue's Blue Enzyme Bullets. In levels Buttons appear in, only one Button appears in each level.
