Wishgriff: I saw a picture of Princess Luna shaking Twilight’s bottle once. What would happen if some shook a genie’s bottle when the genie was inside?
Parcly Taxel: Shaking and rubbing have the same initial effect; the genie is just a cloud of mist, so floats out of their vessel without feeling anything unusual. Once outside and facing their wisher, however, any further shaking sends unbearably great tickles up their misty tails and into their solid half!
Wishgriff: This is also the finished vector of what Parcly did at UK PonyCONLINE: Welcome to the Maneframe.
