Chemitory is a small black blob with yellow eyes and floating, fingerless hands. It wears a pill-shaped suit that is red metal at the bottom and transparent glass at the top. The glass dome holds red and blue pills.
Chemitory first appears in Stage 3 of Patched Plains and reappears in many stages thereafter. It remains stationary, occasionally opening its dome and tossing a pill at Kirby. The pill bounces a few times when it hits the ground and can be inhaled; swallowing it grants Kirby the Doctor ability just like swallowing the enemy does.
If Chemitory is positioned on a different plane from Kirby, the enemy will toss pills across the gap to hit him. Chemitory's aim is sharper than usual when throwing across planes.
Chemitory's name is likely a portmanteau of the word "chemical," a reference to its pills and scientific background, and "factory," referring to its industrial appearance.
