Sounds good, at first, but then I think people would get annoyed by it the same way they get annoyed by random force floors. Plus, Vladimir would need two bottles of Vodka, and Chip would get drunk enough just by drinking a non-alcoholic beer (with still a low percentage), a normal beer would be too much for him. 0% alcohol beer would also work if it gives him a placebo effect. Maybe collecting more than two bottles of Vodka or more than one beer would bring death to the corresponding character.
How about an item called ''saddle", where, in lack of a flipper or fire boot, you can ride a Glider or Fireball across water/fire?
