Thudd

Thudd is one of the enemies in Kirby: Canvas Curse. They are silver, cube-shaped stone-like enemies, and have a face similar to a Kabu's. If Kirby walks under a Thudd, its yellow eyes appear just before falling down. Thudds come in three different sizes: small, medium, and large.

In Kirby: Canvas Curse, Thudds are first encountered in Contrast Cave in Iello Adventure. Their sole form of attack is to fall on Kirby when he goes under their location, much like a Thwomp from the Mario franchise. Thudds cannot be defeated, as putting the Stylus over them merely draws a line, which makes a Thudd more of an obstacle than an enemy. A Thudd is also one of the paintings in Paint Panic.

In Kirby Super Star Ultra, a Thudd makes a cameo appearance as one of Stone Kirby's transformations.

Etymology
Thudd's name is derived from the word "thud," the onomatopoeia for a heavy object falling onto the ground, something that reflects their method of attack. Thudd's Japanese name, Dendon, is derived from the Japanese onomatopoeia for thud, ドン/どん (don).
