— Description of Blockbot from the manual.
Blockbot is a large wind-up toy robot appearing in Kirby Tilt 'n' Tumble. It cannot harm Kirby directly, but it will repel him if he runs into it, and can often be seen blocking passageways. Kirby can make Blockbot move by pressing Switches or performing other tasks. When they walk, Blockbots can also make platforms appear around them, which Kirby will often need to use to move along in certain areas.
Blockbot can be defeated using the Mike or by bouncing between multiples of them in ricochet.
