Dromp is a Rank A Yo-kai of the Tough Tribe.
Dromp is one of the largest Yo-kai seen in the series, being a giant made of brown dirt which has three wavy lighter colored stripes, with fairly short arms ending in four-fingered hands of the same color of the stripes. He has comparatively tiny brown-colored eyes. On top of his head grows a patch of light-colored grass with some flowers.
He really likes mazes and keeps his promises. Dromp appears intimidating due to his enormous size, but he is actually very gentle.
Dromp has the ability to terraform landscapes into personal labyrinths, into which he teleports or traps victims. He then invites them to find their way out, largely for his amusement. To make things even more difficult, he can even obfuscate navigation systems and distort aerial views to make finding your way out close to impossible. Affected victims have been known to wander Dromp's mazes for an eternity.
Anyone Inspirited by Dromp is said to stubbornly refuse to ask for directions, even when hopelessly lost.
Outside of his abilities, Dromp appears to have some size-shifting ability where he can appear at either gigantic size or towering over a basic human.
