Don't let the raw stats fool you. Thick Fat halves incoming Fire and Ice damage, and that completely changes the math for Grumpig. Only weak to Bug, Ghost, and Dark. Part of the Gen 3 roster.
Nothing fancy in Grumpig's spread. It leans special with Sp. Def out front. And you'll get 2 Sp. Def EVs per KO for it. Follows a fast 800K XP curve.
It uses black pearls to amplify its psychic power. It does a strange dance to control foes’ minds.
Grumpig Weakness
VulnerableType-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.
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)
Grumpig is what Spoink becomes. Breed it for Spoink eggs (average hatch time). No compatible partners for breeding via one egg group. Eggs are average hatch time. The evolution from Spoink pushed Grumpig to 470 total stats. Defense saw the largest single gain at +30.
How to Evolve
Breed with Grumpig to get Spoink eggs easily from the Ground egg group. Notable egg moves include Amnesia, Endure, Extrasensory and 7 more.
This is a pure walling set. Lum Berry provides one-time status cleanse so Grumpig sticks around, and the Bold nature reinforces physical wall. Rest handles sustain while Thickfat does work passively.
