Sonic the Hedgehog 2
The first appearance of Whisp Badniks is in Sonic the Hedgehog 2. These Badniks can only be found at routes above the water sections of Aquatic Ruin Zone where they fly around in swarms of three or five. They are usually positioned near jumps where the player has little protection from them. Whisps will start following and fly down to attack the player, but will not follow the player underwater. Also, if they chase Sonic for long enough, they will fly away. However, Whisps can easily be destroyed one by one with the Spin Jump or while charging a Spin Dash.
Sonic Pocket Adventure
Whisps make their latest appearance in the Sonic the Hedgehog Pocket Adventure, as these fly Badniks are featured at routes above the water of Aquatic Relix, which is almost identical to Aquatic Ruin Zone with its gimmicks and Badniks. In the game, Whisps appear now by themselves instead of in groups with three of them. Despite its blue and white appearance, Whisps appear to have same attack pattern.
