Ferrothorn

Ferrothorn (ナットレイ), a dual-type Grass/Steel Pokémon, was introduced in Generation V. It resembles a flattened durian, with a body covered in green spines. Ferrothorn's body is metallic, with three black stripes encircling it, the middle one being triangular just below its eyes. Its eyes have green rims, yellow sclerae, and black pupils. There's a green spike at the top of its head. Long, thin green vine-like appendages tipped with spiky metal disks extend around it. Ferrothorn uses these spiny metal appendages to cling to cave ceilings or walk slowly. They typically dwell in mineral-rich caves, hunting by firing spikes. Their spikes are harder than steel and can pulverize boulders. It evolves from Ferroseed starting at level 40.
