Dynaking the untamed horse is so wild that he does not let Boes shoe him. Boes tries to make friends with him by giving him carrots etc., but the horse ignores Boes. Boes wants to ride Dynaking anyway and finally manages to put a saddle on. Dynakings gets very depressed and is even outrun by a duck. When a green catterpillar hangs infront of his face he runs in panic and thus wins the race in the end.
Boes wil een paard hoefijzers geven maar het dier negeert hem. Hij wil racen maar het dier wil niet en wordt ingehaald door een eend. Hoe kan Boes de race ooit winnen?
