Clamer[1] (クラマー[2] Kuramā?), also known in Japan as Shell Star (シェルスター Sheru Sutā?),[3][4] is an enemy that appears in Sonic the Hedgehog 3. It is a mass-produced, clam-based Badnik model created by Dr. Robotnik.



The Clamers, as their name states, are Badniks that resemble blue and yellow-colored clams with a pair of black eyes and a cannon hidden inside it.

Game appearances

Sonic the Hedgehog 3 & Knuckles

In Sonic the Hedgehog 3 and its lock-on addition Sonic the Hedgehog 3 & Knuckles, Clamers are encountered only in Carnival Night Zone, where they remain stationary. When the player approaches one, the Clamer pulls out its cannon and fires spike balls in a straight line.

When using the Spin Jump on a Clamer's shell, the playable character will bounce off it diagonally, like a Spring. To destroy a Clamer, the player's best option is to either hit it from behind or roll into them. However, it is also possible to defeat them from above with the Insta-Shield.

Sonic Rivals

In Sonic Rivals, a Clamer appears as a collectible card.

In other media

Sonic the Comic

Clamer appears in Sonic the Comic as part of Doctor Robotnik's badnik army. It was about to be melted down by Robotnik so that its metal could be used for a new improved badnik, after Sonic had foiled one of Robotnik's schemes.[5]


  • In LEGO Dimensions, Clamers appear in the Carnival Night Zone portion of the Sonic the Hedgehog world. They open and close their shells periodically, but do not attack players when they come near.
