It uses black pearls to amplify its psychic power. It does a strange dance to control foes’ minds.
Grumpig Weakness
Type-wise, Grumpig takes extra damage from Bug, Ghost, and Dark. Thick Fat reduces Fire/Ice damage, further improving the defensive spread. Grumpig's special bulk (base 110 Sp.Def) helps absorb special-type weaknesses, though physical moves exploit the lower Defense.

Grumpig Guide
In Ultra Sun & Ultra Moon, Grumpig looks average on paper at 470 BST. But Thick Fat is why it sees play. Build around that and it pulls its weight. C-Tier on our tier list. Psychic with Leftovers is the standard set.
In Ultra Sun & Ultra Moon, Grumpig's biggest threats include Heracross (Bug), Misdreavus (Ghost), and Houndoom (Dark), all carrying super-effective STAB moves.
Grumpig gets Thick Fat, Own Tempo, and Gluttony. But Thick Fat is the one that matters. It's the centerpiece of every viable set. Build around that.
Grumpig is a special attacker with base 90 Sp. Atk. Enough bulk to take a hit or two, too. Speed tells the real story. Base 80 Speed is workable. Faster than some, slower than many.
In Ultra Sun & Ultra Moon, the best way to handle Grumpig: Super-effective STAB from faster Pokemon is the simplest answer. Bug, Ghost, and Dark-type attackers hit hardest.
