You can pick a halloween charm to be on the bottle (bat, skull, pumpkin, candy corn etc.)
Potion color can be changed

$60 to get your character drawn in the bottle
+$20 if you want your character in a halloween outfit
+$10-$30 to add background otherwise it'll be a simple halloweeny patterned/colored background
