Flobby is a member of a trio of actors who perform at weddings, birthdays, parties, and the like. His two colleagues are Bobby and Tobby Rotten. He is the shortest of the bunch and cannot speak, which is not an impediment for his natural inquisitive and joyful behavior. He can be seen mouthing the words to "We Are Number One" during the musical sequence of "Robbie's Dream Team".
Although he plays the role of a villain, he does not seem to have bad intentions whatsoever, and apparently does not even know what being a villain is about.
Flobby looks very similar to the other Robbies. He wears a two-piece suit of maroon and purple with gold pinstripes, formal shoes, a navy blue shirt with cuffs and cuff links. He is the shortest of the bunch.
