Bernie the Bee is a bee that floats around the Zen Garden in Plants vs. Zombies 2. He appears whenever there is a plant whose growing time can be sped up, and tapping on him and picking such a plant will shorten the time on the plant's growth timer. After speeding up a plant, he will take a nap and recharge for 30 seconds.

In the 2.1 update, there was a glitch where he either sleeps in a wrong spot, or does not show up at all.
He will only appear in the Zen Garden if there are plants that can be sped up.
If he does the last pollination possible at that moment, he will go to sleep and won't wake up until you dig up a plant. If the Zen Garden is exited out of or if the player goes to the Almanac or the Shop from the Zen Garden, he will disappear and doesn't come back again until there are new plants to be watered.
When he goes to sleep while facing left, his sleeping text is printed backwards.
There is sometimes a glitch where he will sleep much less than its usual sleeping duration. However, this is very rare.
If he is tapped while sleeping, he turns over in his sleep, raises his arm up and throws it down (so as to wave off the player), turns back over and continues to sleep normally.
If the player taps on Bernie, then does not do anything for 5 seconds, Bernie will shrug his shoulders and cancel the action.
While he is sleeping, he usually emits his sleeping text 10 times before waking up.
When he speeds up a plant, he says "baiser," which is French for "kiss".
