i could animate it in sfm, and maybe make a WMOD soundfont cover of a cruel angel's thesis from neWAHn sega genesis as the theme song. the mystery character, until the episode where he/she is revealed, would be a black shadowy figure, and you could hear a sound of a robe coming off (using something like a towel for foley) as it cuts to the party's reaction (wario, d3, sonic, and anyone else who joined them before then), and reveal the character, maybe make the first part like the "I'm..." and the reactions the end of an episode, have it cut to "to be continued", and have the reveal the beginning of the next episode.
