It's Great To Gain

"Is there a way to stop the side effects?" you ask about the Wishing Powder still feeling embarrassed how your wish back fired and gave you thicker legs and butt.
"No," Swizzle answers then his face lightens up," but I can trade your Wishing Powder for a different potion that grants some wishes. Or you could keep the Wishing Powder and make a small wish to undo the wish rebound effect."
"Sound good to me," You tell Swizzle," epically if I get mad again and wish for some revenge."
"You have to be careful with revenge," Swizzle warns you, looking right into your eyes. Swizzle snaps his fingers and you return to your normal weight," it almost always comes back to haunt you."
You look down at your clothes to see that they fit again and look back at Swizzle's eyes and nod your head in agreement. You then take the Wishing Powder out of your pocket and hand it to him and he hands you a small vial of red powder that says: Want Powder. You read the instructions:
Sprinkle Want Powder into liquid, stir, take a sip and say or think of what you want. Wishes must have the word 'want' in the sentence. Example: 'I want a candy bar.'
"Seems easy enough," you say under your breath.
"Be careful," Swizzle warns," the Want Powder is also powerful."
"Thanks again Swizzle," you smile and wave to Swizzle and walk out of Notz and Yeps.
You walk down the mall's hall and soon find yourself looking at Mary. You then see that there's a swarm of guys looking at her and her expanded rear end. She's barely keeping a straight face as all the guys drool and shout about how sexy her new look is.
"Darn it," you mutter to yourself and remember what Swizzle said.
