Trick or Treat

Halloween is coming. I see some crazy goods for costume parties, pumpkins and sweets in shops here. I saw a woman bought plastic axes the other day. When I was young, we didn't have Halloween culture in Japan. The celebration event came from Western countries, and now you can see some goods and sweets at shops as a selling strategy. I know Halloween but I have no idea what Halloween is like exactly.

I got comic magazines with free gifts today, they were an auful bloody tooth and a black spider I hate. Are they useful for Haloween maybe???
