"Demon Castle Special: I'm Kid Dracula" and Kid Dracula are spin-off titles to the Castlevania series on the Famicom and GameBoy respectively which are light-hearted platformer titles starring Dracula's son, Kid Dracula, as the main protagonist.

One boss was shown only as a spiky-looking silhouette against the castle wall with the text "?" which we now know is more than likely Kid Dracula (Dracula-kun in Japan) from the game of the same title in English.

Dracula's castle was revealed at the same time as the two vampire hunters and was shown to feature stage hazard bosses from the classic Castlevania games including Death, the Mummy, a Werewolf, Carmilla and Dracula himself - who can be summoned under currently unknown circumstances.
