|“||The young Thornsbys think they're hot stuff, but the middle-aged Thornsbys definitely have more wisdom. And the old Thornsbys don't really care what you think about them.”|
|— Figurine description • Kirby and the Rainbow Curse|
Thornsbys come in two colors: burgundy and yellow. A burgundy Thornsby is a cylinder with brown rings around its top and bottom. It has constantly closed, angry eyes and a black impression resembling a moustache. It has a spike growing out of its top, bottom, left, and right sides.
A yellow Thornsby is a slightly rounder cylinder with orange rings around its top and bottom. It has constantly closed, passive eyes, a tiny mouth, and a black impression resembling a moustache. It has handle-like arms on its left and right sides.
Thornsbys appear exclusively in the stage Volcanic Panic. They are found in stacks that often block entire passageways. If Kirby attempts to attack a burgundy Thornsby, the hero will take damage. If he attacks a yellow Thornsby, however, every enemy in the stack is destroyed.
Thornsby's name is derived from the word thorn, referencing its spiky body.
- Thornsby is similar Stactus, an enemy in Kirby Mass Attack. Both are spiky enemies that stack upward, and both enemy stacks have one weak spot that is denoted by color.
