Yadokka (ヤドッカ?)[1] is an enemy that appears in Sonic Advance 3. It is a mass-produced, hermit crab-like Badnik model created by Dr. Eggman.



The Yadokkas mostly resemble Turbo Spiker Badniks.


The Yadokkas only appear in Twinkle Snow. In gameplay, the Yadokkas 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 Yadokkas will be defenseless against any of the playable character's attacks.
