Shell Spikes are a sub-species of Spikes that first appeared in Super Mario Bros. 3D. They are known to spit out up to three Koopa Shells at a time which they then will indevidually throw at the player, once they have thrown all three they spit out three more.

They can throw Green Koopa Shells which just work like when the player kicks a shell, Red Koopa Shells which can turn back into Koopa Troopas if the player stops them and finally, Blue Koopa Shells which allow the player to turn into Shell Mario if they stop it.


Shell Spikes are lime green coloured Spikes, their hair is a slighly lighter colour blue than an average Spike and their lips are a pale pink colour.

Game Appearances

Super Mario Bros. 3D

Shell Spikes first appear in World 3, where they only throw Red and Green Koopa Shells, after this they are encountered in World 5, 6 and Special Worlds 6, 7 and 8 where they will throw Blue Shells aswell.

They are known to jump to a new location if the player walks near them or even try to flatten the player on rare occasions.


  • They were originally going to throw Yellow Koopa Shells aswell, which would glide along. It is unknown why this feature was removed.
  • If the player is Shell Mario and they duck inside their shell right next to a Shell Spike, the Shell Spike will pick the player up and throw them, not knowing that the player is inside the shell.
