Sunkern

The crappiest Pokemon in terms of stats, that is still the most athletic Pokemon ever. It can max out each stat for the Pokeathalon in Heartgold and Soulsilver.

Sunkern is a mostly yellow, seed-like Pokémon with a small sprout growing out of its top. It has triangular, spike-like protrusions on top of its head, encircling the sprout. Its body has three broad, brown, vertical stripes. Two of the stripes start jaggedly above Sunkern's dark eyes and continue downward. The other stripe is directly below Sunkern's mouth. Since Sunkern's eyelids are brown, the brown streak patterning appears uninterrupted when Sunkern's eyes are closed.
