Hariisen (ハリーセン Harīsen?)[1] is an enemy that appears in Sonic Advance 3. It is a mass-produced Badnik model created by Dr. Eggman.


The Hariisens resemble pufferfish.


The Hariisens only appear in Twinkle Snow. In gameplay, when the player approaches a Hariisen, it will begin to puff itself up, revealing spikes on its body that point in six directions and then firing them. Once the Hariisen is spike-free, the player has the opportunity to attack them unharmed before it puffs itself up again with more spikes.
