"The Search for Bruce"
Episode transcript (provided by phantym)
The toads have perfected a transporter, allowing them to beam toads from one place to another. They immediately start beaming toad troopers onto the Righteous but are scared off when what appears to be the ghost of Bruce appears and stomps around their base.
KOMPLEX picks up on this and sends out a fake message from Bruce to the crew, trying to get them to go to sector five. The real Bruce appears, explaining how after he was zapped to another dimension, he immediately began working on a teleportation device and was just finishing it when the toads got theirs working, and the two clashed somehow, so he is only able to project himself enough so that he looks transparent. He explains that the message they got was fake, but Bucky decides to go to sector five anyway, knowing it's a trap but not having anything better to do.
At sector five, the crew infiltrates the toad base to destroy the teleportation device. Bucky, Bruiser, and Bruce get to the machine's control room, and Bruiser realizes that if he destroys the machine, he'll lose Bruce as well. Bruce tells him to destroy it anyway, and Bruiser does so (Bucky has been knocked unconscious by a pipe at this point). They all escape, though Bruiser is saddened that he has lost his brother a second time.
