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 can perform odd dance steps to influence foes. Its style of dancing became hugely popular overseas.
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.
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.
Find one free turn for Nasty Plot and Grumpig can run through teams. Timid nature leans fast special, Thickfat supports the sweep, and the remaining moves stops anything from walling it cleanly.
