The Yadokk[1] (ヤドッカ[2] Yadokka?) is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, hermit crab-based Badnik model created by Dr. Eggman.



The Yadokks mostly resemble Turbo Spiker Badniks.


The Yadokks only appear in Twinkle Snow. In gameplay, the Yadokks move back and forward for the ground. When the playable character approaches them however, they will launch their spiky shells directly upward in an attempt to hit the playable character while they jump. After firing their shells however, the Yadokks will be defenseless against any of the playable character's attacks.
