Twilight is trying a new spell
Twilight: alright I'll need is to test on something for this growth spell. Maybe an apple will do the
trick.
She placed the apple down and zapped it, but nothing happened.
Twilight: what?! Ugh, I can't believe this spell didn't work, oh well I guess I'll try to do something
else.
She leaves the apple there and Apple Bloom saw it.
Apple Bloom: hey, who's leaves a perfectly good apple like this in the middle of nowhere.
Apple Bloom grabs the apple and goes home.
Applejack: howdy sis, how's it going?
Apple Bloom: nothing just brought an apple to home. Say, why don't we shared the apple together
Applejack: sounds good, let me just go grab a knife.
Applejack grabs a knife and cuts it in half
Applejack: well, down the hatch
Applejack ate the half apple and Apple Bloom ate the other half, until they felt something.
Apple Bloom: *groans* I don't feel like myself
Applejack: me either
That is until they felt pain in their stomachs, their abs popped out and their pecs grew big.
Applejack: sis, what's happening to us?!
Apple Bloom: I don’t know?!
Applejack arms grow huge and Apple Bloom legs burst of muscle
Apple Bloom: dang our muscles keep getting bigger.
Applejack: I know, and it feels good!
Apple Bloom flex her arms and they got bigger and Applejack legs became muscular.
Applejack: oh my applesauce! Look at us sis!
Applejack: we're so big
They flex each other's muscles
Applejack: Maybe we should go to the muscle competition to win, little sis!
Apple Bloom: I agree with you big sis!
They both hugged
The End
