The Tweerk was a Clicket starship in service during the 24th century.
On stardate 57818.4, the Tweerk rendezvoused with the USS Cerritos to deliver a map of the Romulan Neutral Zone. However, the Clickets attacked Captain Carol Freeman after she thanked them for the map, and a further subsequent misunderstanding led to a brief exchange of phaser fire between the vessels.
