Answer:
The theme of the tale "Blockhead and the Queen Bee" is the reward for having noble acts.
Step-by-step explanation:
The main theme of "The Queen Bee" is the reward in this case, by nature, for acting well along the way.
Blockhead prohibited his brothers from destroying an ant hill, killing ducks, and destroying a bee hive.
At the time of fulfilling the challenges that the old man had imposed, the two brothers could not achieve it, becoming stone. While Blockhead got the help of those animals who had saved their lives. He manages to marry a beautiful young princess and thus receive the kingdom.
Nature was grateful to him, and for that he was rewarded.
