Betcha the ghost-beeswax candles let you see spirits within their range of illumination. Very handy for a seance.
Ooookay, Danny has moved to Gotham for <insert reason here> and is faced with a problem. Yes, Gotham has higher levels of ambient ectoplasm than your average city, but it's nowhere near those of Amity Park who has a goddamn artificial hell mouth smack in the center of it. Also, the ectoplasm which IS there is contaminated with some nasty shit that makes Danny feel ill when he takes too much of it in. Having his friends back in Amity Park ship him flasks of pure ecto on the sly is difficult to say the least, so he starts thinking about ways to both concentrate and purify Gotham's ecto so he's not one shipment interruption from being in really bad shape.
He get's his solution from Sam. On his bi-weekly video call with her and Tucker, she gets to ranting about bee conservation. Tucker makes a joking comment about honey being basically bee vomit, and Sam tears into him saying "That is a gross oversimplification at best and outright bee-slander at worst!" This perks Danny's curiosity, so he looks up the biological process by which bees turn nectar into honey...and he's found his answer. Blob ghosts are basically the filter feeders of the Ghost Zone/Infinite Realms. If he can get a bunch of them to behave kinda like honey bees, his ecto supply should be assured.
It works...a bit too well...
Now Danny has a swarm of glowing green honey bees that are roughly the size of carpenter bees buzzing happily about him. Their queen is roughly the size of a large hummingbird. He heaves a weary sigh and starts looking up how to ACTUALLY keep bees and making skips out of ghost-friendly material for them to build their hive in on top of his apartment building.
But, won't Danny get complaints from his neighbors? Here's the kicker. Unless you are a 1) ghost, 2) halfa, 3) wearing specialized Fenton Ecto-Visual Goggles or 4) a mage, you cannot see, hear or feel the bees! They're buzzing around Gotham happily, slurping up the ecto to take back to the hive for processing. And they slurp it up from EVERYWHERE...including certain people.
Jason Todd is slightly confused but not about to look a gift horse in the mouth. Over the last few months, the Pit Rage has been decreasing gradually. He doesn't think much about it until he shows up at the BatCave for an all hands meeting that has been called because John Constantine needed to brief them on something...only for Con-job to take one look at Red Hood and shout that he's "COVERED IN FUCKING BEES!!!"
