The Blue Slime Lamp blueprint becomes available for purchase from The Lab's Builder's Shop two days after purchasing the Pink Slime Lamp blueprint. It costs 850 to purchase.
The Blue Slime Lamp is used as decoration so has no immediate functional use. However it can provide a small amount of lighting in The Ranch.
Like all decorations it can be stood on, potentially allowing it to be used in conjunction with the Jetpack to reach higher areas.
