Boom Stompers (ドスドス, Dosudosu) are enemies from the Kid Icarus series. They resemble large seeds made of rock.
In Super Smash Bros. 3DS/Wii U
Boom Stompers appear as enemies in Smash Run. They walk around on two stubbly legs and pound the ground with their body to try and crush the player. Their weak point is the small plant on top.
A giant rock bestowed with the gift of life. It usually stays still - as rocks do - but if it catches sight of you, it'll slowly move after you and try to stomp you into the ground. Its stomping also causes shock waves that will harm any fighters in the vicinity. Its weak point is the little leaf on its head!
