Trivia

 * This is considered one of the more coveted upgrades to experienced players, due to being a hard to unlock tower, and being very expensive.
 * This upgrade is similar to the Beekeeper Pro's ability in Bloons TD 5, but the notable differences are:
 * It is an upgrade in BTD4 iOS, but it is an ability in BTD5.
 * It releases four bees at a time in BTD4 iOS, but it releases one bee at a time, and a swarm of bees in BTD5 when the ability is used.
