Thwunk was Bender's robotic dog that he used to (literally) attract other fembots to him as he was magnetic.
- Thwunk is identical to Bender's other robotic dog, first seen in "Jurassic Bark", Robo-puppy. Robo-puppy is black with a dark purple visor, whereas Thwunk is white with a light blue visor.
