King Jozef gives a lesson in royal greeting techniques and complains about his diet, so the Grimms brothers, who now hope to learn flying by setting in eggs, invent a slim-making potion; alas it makes the king's head drop off, however not fatal, while the other brother Grimm only thinks he's a bird fledgling. Just then the Kardigraaf (in Dutch a contamination of Cardinal and Count) makes his annual inspection, for he once won a hunting contest and may now succeed to the throne once the king is headless, so that must be hidden for him; alas he already knows from his spy, a domesticated microbe. While the Kardigraaf looks for the decapitated king, he already tells everybody they'll get new names in his reign. Kulderzipken gets the remaining Grimm to work on an 'inverted potion' while he guards the 'hatchling Grimm' and 'two-part king' on the castle roof...
