LightningDust strikes back

The potion

After being kicked out of wonderbolts academy LightningDust didn't know what to do next. Her dream ever since a filly was to become one and because of one mistake her chance was all gone. Lighting dust burst into tears and after a while she agreed that a walk in Postville could calm her down. As she walked around she nothing that interesting around. But one thing caught her eye. Zecora' s potions. She came closer to the booth and looked through the potions. Nothing she needed. Lighting dust was trying to reach a potion and sneezed which caused the potion to fall over and spill. But behind that potion was another potion called 'pony change' she read the potion carefully after she was done cleaning her mess. Caution! This can cause danger. This potion allows a pony to be 2 different pony whenever they want but cannot keep changing or can stay forever as their other self not their true self. LightningDust studied it carefully and  grabbed a hoovefull of coins. Zecora looked at her "This is not for sale didn't you read the caution sign? She asked. LightningDust took twice as much. "Would you like a bag for that" "sure why not" she said as Zecora handed her the bag with her potion. Lighting dust raced back home excited to open the potion...........
