A Honeystorm can be summoned from the pad near the Brown Bear by anyone who has discovered four types of Legendary Bees. When summoned, the game will announce "<playername> has summoned a Honeystorm!", a golden fog will descend, and lots of Honey tokens will begin appearing randomly across every field. The storm lasts for 20 seconds and may not be called by the same player for another four hours. It can also trigger randomly; in that case, the game says "A honeystorm has been summoned!"
When a Honeystorm is summoned, there is a sound effect of a deep voice saying "Honeystorm", and the honey tokens make raindrop-like noises when they appear. It is easier to hear these sounds if you have the music turned off.
Fields with bigger flowers give larger honey tokens. However, unlike with flower-generated Honey tokens, your Luck does not affect the value of the Honeystorm tokens, so their value can seem lower than what you're used to.
There was a short-lived bug on 5/26/2018 that caused the Honeystorm to be accidentally removed. If you encounter a server without a Honeystorm pad, leave the game and come back.
