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.

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 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.

Breeding's the move. Amnesia and Endure give Grumpig options it can't learn any other way, and coverage across 9 types already covers a decent range on top of Future Sight and Dream Eater. The egg moves push it further.

    Step 2Grumpig
  • 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.

  • Grumpig's biggest threats include Heracross (Bug), Misdreavus (Ghost), and Houndoom (Dark), all carrying super-effective STAB moves.

  • Spoink evolves into Grumpig at level 32. Grumpig is the fully evolved form. It sits at 470 BST in its evolved form.

  • 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. But the speed tells the real story — base 80 Speed is workable — faster than some, slower than many.

  • Grumpig appears in 15 games, including Ruby & Sapphire, FireRed & LeafGreen, and Emerald.

Debuting in Ruby & Sapphire, Grumpig appears in 15 games across 7 generations. A reliable presence in most mainline games, typically found through wild encounters.
