Mammoth Miss is the former girlfriend of Mammoth Mutt. She is the only female member of the Space Canine Patrol Agents (aka the SCPA). Her power to inflate herself proved useful in a number of way. She inflated a series of cat balloons that were left as a gift by Krypto. Also, during a mission involving the stopping of over-sized fleas, she used her inflation power to float over the situation, and radioed her fellow members about various conditions. 
- Transformation: Mammoth Miss has the ability to inflate herself with air like her late boyfriend, Mammoth Mutt.
- This version of Mammoth Miss (Earth-One), including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985-86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
