An ink bottle is a cyan pot of rainbow-colored ink. It has an oval window on the front which shows the bottle's contents. The bottle's top is covered with a black lid.
When Elline draws rainbow ropes, the Rainbow Ink meter depletes. If Kirby waits long enough, it will refill automatically. An ink bottle will instantly refill the meter upon collection, making it useful for drawing longer lines and going longer distances on the rainbow ropes. Ink bottles can also be important when Kirby has no ground to land on, primarily in Blue Sky Palace.
