Bat Twin Pharmacy

So since a few of my other town ideas I've drawn already, I'm going to start off a little later on.
Idea#1
A pharmacy run by 2 bat twins.  The store is split in half by an obvious decor change.  The male twin believes in only magic being useful as medicine and wears the hides of of animals and has multiple bottles of unknown liquids labeled with different afflictions they cure.  The area where he works has a large couldron and and a wall of miscellaneous strange ingredients.  The female twin believes only in science.  She wears pants, a sweater and a lab coat, both of which have magnets that attach to each other on her wings, giving the illusion of normal clothing.  Her side is kept hospital sterilized with multiple scientific instruments for drug administration.  Their work area is a table with a large chemistry set.  Rows of drugs and pills line their side of the store.  Both sell medicines/potions for normal illnesses and both also sell more "abnormal" drugs as well.  The 2 fight over which actually works, magic or science, which ends in them "testing" their products out on each other. Hope that you never get caught in the crossfire.  Their wares are fast acting and usually take a day to wear off.  Due to their fights almost always getting down to tfing they have been banned from the arena, as the owner got tired of having to refund people  for being tfed.  Their tf potions/drug have one side effect beyond TF is that the genes of whatever anthropomorphic animal you have been tfed into becomes a dominant in specific genes, mainly in appearance, meaning that if a child were concieved while either parent was tfed, the child, even after the person changes back, would end up with the traits of said animal. Also, due to the genes being dominant, cause the child to also have children of said species.

Alright that was idea#1 hope you liked it
