Drisame (ドリサメ) is an enemy Badnik that appears in Sonic Advance.
Drisame is a shark-like robot similar in concept to Jawz from Sonic the Hedgehog 3, albeit with a drill mounted on its face. They are hidden in the icy walls underwater in Ice Mountain Zone, and, when approached, they break through the wall and dive away. The player can destroy this robot with a Spin Jump or any form of attack. This type of "surprise attack" has been used before by the Grounder Badnik, from Aquatic Ruin Zone.
