Kasplat
These Kremlings are stockier in build, wear sunglasses and leather jackets, and have color-coded hair. The hair of these kremlings correspond to the color of blueprint that they carry on them. If you kill them, they drop a blueprint of the same color as their hair, however you can't pick up the blueprint unless you are the correct kong (just like bananas and banana coins). If their hair is white, then it means you've already gotten the blueprint. Kasplats attack with their fists and by making shockwaves by pounding the ground. They can take considerably more damage than most other enemies, usually requiring about 15 launcher shots or 5 oranges.
