Caught in a Trap. Mia and her dad yellowhead have a visitor. Grandma Nanna drives up to her campsite on her rattling motorbike and invites herself to have a coffee. Nanna is a funny bird. She is half-blind without her glasses, in addition to that she is maddeningly adventurous and a keen gamer. In addition, she unreservedly sacks everything that lies around unsupervised and that seems halfway useful to her. Stupidly, this is also the case with Feuerkopf! He fell out of a tree and not only completely lost his memory but also turned his personality into the opposite. The hotspur has become a cuddly toy that feels good in grandma's company and can't imagine anything nicer than being fed biscuits and accompanying the old lady. Of course, this not only horrifies his two goblin friends, but also Mia: all the more so when, unfortunately, Siebenpunkt also falls into Nanna's clutches. She wants to secretly take her prey home with her!
