It seems that the Hello Kitty beehive bees succumbed to the humiliation of having to be known as the Hello Kitty bees. At the time, Bill Bird was confused about why his bees were swarming even though the evidence was obvious as I explained:
The answer is simple. You’re making the bees live in a freaking pink Hello Kitty bee hive and they figured it out. It would make anybody angry and want to swarm. Of course, as anyone that would think it was a good idea to build a Hello Kitty bee hive in the first place, they try to rationalize the new found aggressiveness of the bees to something else.
