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. Sunkern is known to be very weak. Aware of its weakness, it only feeds until it evolves. Sunkern can be found in grassy meadows.
