Potion? No, but I can probably cook up something for ya that might do a little better... let's see what i can cook up:
Get yourself the following ingredients:
Aloe Vera, bamboo, catnip, fern
Get them as live plants, if you can. don't take the whole plant, but definitely get a section from each about the length of your hand, from wrist to finger tip (yes, you can get smaller chunks, as long as you have a goodly amount, at least in as much as I described). *Even if you can't get all live plants, get WHOLE LEAVES. Don't get preground powder.*
If you get them ALL as live plants, dry them all together. If you have a gas stove with a pilot light, put them all on a plate together and leave it over the pilot light for as long as you can. The aloe will probably take the longest to dry, since it doesn't come in small stalks usually. If you get some fresh and others already dried, dry each of the live ones separately.
Once you have a bunch of dehydrated plants comes the hard part. At least, hard on your paws. You need a mortar and pestle. And you need to grind each plant into a find grain, then take the fine grain of all the plants, mix it, and grind it into powder. You MUST focus on what you want out of it while grinding, or it will just be a generalized 'luck charm', like a lucky rabbit's foot.
After this is done, go to the store and get some foot deodorizing powder (If your dad already has some, even better, just use that. Foot powder for athlete's foot works perfectly well, also). A large bottle would be best. Carefully pour the powder you made into the foot powder bottle, seal the bottle, and shake the bottle for about 20 minutes. You can take breaks, it just needs to be evenly distributed.
NOTE: You don't HAVE to tell your dad you're doing it, but if he's amenable to magic, doesn't care either way, or knows you've been practicing and simply thinks it's a joke, feel free to tell him.
