Miumiu is Professor Moshimo's young and beautiful assistant, as well as his fiancee. She can frequently be seen helping her fiancé in his work although especially when she isn't trying to pull him away from it with her affection. Despite the vast age difference between the two, her love and attraction to the professor are clear, as shown when she continually pulled Moshimo away from a holo chat with Robotboy to make out with him. She appears to be on good terms with Tommy and Lola as well for Robotboy while Gus on the other hand she has only ever been seen frowning at.
