Flake, Twirl, Twix

I like Cadbury's Flake Chocolate Bar, except that it's quite messy to eat. I recently rediscovered Twirl Bar, which is like a Flake encased in a chocolate shell. That makes it the perfect way to eat a Flake neatly. I also get Twirl and Twix mixed up because they both start with "twi", even though they're different chocolate bars and have different packaging.
