Yuugibot

A friendly, just-for-fun bot for Yugioh fans. He's two perfect boys in one! I wonder who's talking..? Yuugibot can respond to his own name in certain contexts, posts certain images or videos upon request, and loves to cheer people up and make new friends.
Yuugibot was created by @greed-the-dorkalicious on Tumblr. He's my first bot, so bear with me please! Yuugibot's features include the following:
y!yeehaw - Posts the "YEEHAW!" Joey image.
y!hats - Posts the "Magical Hats button" image.
y!jimbo - Posts the "Looks like you're going to the Shadow Realm, Jimbo" image.
y!roll - Rolls a d20.
y!positive - Posts a motivational message.
y!think - Tells you what's on his mind.
He also responds to his own name in various contexts, including "hello", "good morning", "goodnight", "thanks", and "I love you", and he can post Passionate Duelist or Kunai Wit Chain upon request.
In addition to this, Yuugibot has a few hidden commands. I think it's more fun to let them be a surprise, but for those who would like to know, a full list can be found here.
