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.
| Damage | Types |
|---|---|
| 2x (Weak) | Bug, Ghost, Dark |
| 0.5x (Resist) | Fighting, Psychic |
