All "Royal Cookpal" monsters are mixes of a recipe and a royal position (Princess, Knight, King, etc.).
Despite being high-Level monsters, the "Royal Cookpal" monsters have generally low ATK and DEF, but when the opponent Summons a monster, they can return themselves to the player's hand in order to destroy the Summoned monster. They can be quickly Special Summoned back with "Wonder Recipe", creating a Summon-Lockdown. Furthermore, all "Royal Cookpal" monsters have an effect that allow them to double the ATK of another "Royal Cookpal" in exchange for not attacking that turn, allowing a "Royal Cookpal" to reach up to 4800 ATK.
