Kyacchaa (キャッチャー) is a spider-like Badnik that appears in Sonic Advance 3. This Badnik is very similar to the Grabber from Sonic the Hedgehog 2.
These Badniks are found only in Cyber Track where they will hang from ceilings, waiting for their prey. When the player comes near them, they will move to where the player is and drop down on them to grab them. Unlike Grabbers, they will simply harm the player and repeat their attack pattern rather than pulling them in place and self-destructing.
