Mini and Mum are nearly identical in appearance, both of them appearing as small ovoid robots. However, one of them is blue with a single horn on his head, while the other is green with two horns on his head.
Mini and Mum appear to have similar thought processes. They are helpful to their captain, who would be lost without them. While not as smart as Whisker, Mini and Mum are more alert and scheming than they appear.
Powers and abilities
Mini and Mum are both capable of independent levitation.
After the storyline was rebooted following Worlds Collide, Mini and Mum became virtually identical to their game counterparts.
Mini and Mum's names are a play on the word "minimum."
Despite their appearances, there is no confirmation of who is who between Mini and Mum. Writer Ian Flynn on the Sonic the Hedgehog comic series and its spin-offs assumes Mini is the green one and Mum is the blue one, but he does not know that for a fact.
