Sam & Cat
He is seen almost every time Sam and Cat are at Bots Bungle is apparently still not over him but tolerates being around him.
As a robot Tandy doesn't have much of a personality he is programmed to be polite but he is still a misanthrope someone who hates humans.
Tandy and Bungle may have used to date sometime before being seen on the show at the time she was mad at the mistakes he made such as forgetting her birthday they are currently friends but Bungle is still not over him.
