Ferroseed

Ferroseed (Japanese: テッシード Tesseed) is a dual-type Grass/Steel Pokémon introduced in Generation V. When threatened, it attacks by shooting a barrage of spikes, which gives it a chance to escape by rolling away. Ferroseed absorbs the iron it finds in the rock while clinging to the ceiling. It shoots spikes when in danger.

It evolves into Ferrothorn starting at level 40.
